CVE Severity Published▾ Status Exploitation Description
CVE-2026-118383 Critical 2026-11-10 Not applicable No public exploit A use-after-free in the replication component of MongoDB Server can occur when a newly elected replica set primary completes catch-up. The condition can be caused by requests that do not require authentication, and may result in the server terminating unexpectedly or, under certain conditions, arbitrary code execution in the context of the server process. Replica set members are affected, including the shard and config server replica set members of sharded clusters; standalone mongod instances are not.
CVE-2026-87110 Medium 2026-10-09 Not applicable No public exploit An unauthenticated user with network access to the Ops Manager web port can repeatedly request monitoring endpoints that perform costly work without rate limiting. This can temporarily slow other traffic served by the same process while requests continue.
CVE-2026-87109 Medium 2026-10-09 Not applicable No public exploit An authenticated Ops Manager organization member can retrieve another member's pending authenticator enrollment seed through user-listing endpoints while that member's enrollment is unconfirmed. This results in disclosure of secret authentication material to another member of the same organization or project.
CVE-2026-87108 Low 2026-10-09 Not applicable No public exploit An authenticated Ops Manager user with a read-only project role can retrieve a daily host monitoring record associated with a different project when they possess the required record identifier. Insufficient ownership validation can expose deployment metadata, including host and configuration details.
CVE-2026-107325 High 2026-10-08 Not applicable No public exploit Improper validation of a BSON array length in the MongoDB Go Driver can cause an out-of-bounds index and runtime panic when an application calls bson.RawArray.Validate or bsoncore.Array.Validate on a malformed four-byte array. An unauthenticated actor who can supply raw BSON array data to an affected application may terminate an unprotected application process, causing a denial of service. No confidentiality or integrity impact has been identified.
CVE-2026-107324 High 2026-10-08 Not applicable No public exploit An integer overflow in BSON value-length handling in the MongoDB Go Driver can cause a runtime panic when an application validates or accesses a malformed BSON document. An unauthenticated actor who can supply BSON bytes to an affected application may terminate an unprotected application process, causing a denial of service. The driver's server-monitoring path contains panic recovery and is limited to server-selection failure.
CVE-2026-106438 Medium 2026-10-08 Not applicable No public exploit An incorrect calculation in Decimal128 string parsing in the MongoDB C Driver can accept certain over-precision inputs containing leading zeros instead of rejecting them. This produces a value different from the supplied text. An actor who can provide a decimal string to an embedding application, including through Extended JSON parsing, can cause the application to store or use an incorrect numeric value.
CVE-2026-106437 Medium 2026-10-08 Not applicable No public exploit The BSON buffer-reservation API in the MongoDB C Driver can record a length smaller than the five-byte BSON minimum. Later append or comparison operations can underflow unsigned length calculations and read or write outside the document buffer. An actor who can influence the length supplied by an embedding application can cause the application to terminate or read or corrupt adjacent process memory. Reaching this issue requires the application to pass an undersized value to bson_reserve_buffer and then perform an affected operation.
CVE-2026-106436 Medium 2026-10-08 Not applicable No public exploit The BSON encoder in the MongoDB PHP Driver does not check some return values after a document exceeds libbson's size limit. This can leave the encoder in an invalid state. An unauthenticated actor who can cause an affected application to encode an unusually large data structure can terminate the PHP worker or cause the resulting document to omit fields. No MongoDB server connection or database authentication is required.
CVE-2026-106435 Medium 2026-10-08 Not applicable No public exploit The MongoDB Python Driver's binary accelerator can read outside a buffer when an application decodes malformed BSON containing a truncated regular-expression element without a trailing NUL byte. An actor who can supply BSON to the documented decode or decode_all API can cause the application process to terminate when the C extension is loaded. The driver's normal database wire-protocol path does not reach this code.
CVE-2026-106433 High 2026-10-08 Not applicable No public exploit Improper state management in MongoDB libmongocrypt can cause provider-specific data to be treated as an incompatible type when cleaning up a key document containing duplicate masterKey fields. An authenticated actor who can modify key vault documents, or a server that returns such a key document, can cause invalid memory access and invalid frees in the client process. This can terminate the application or corrupt process memory.
CVE-2026-106432 Low 2026-10-08 Not applicable No public exploit The BSON encoder in the MongoDB PHP Driver converts a string length to a 32-bit value without validation. When an affected application encodes a string near 4 GiB, the allocation size can wrap while the copy operation uses the original length. The resulting heap buffer overflow can corrupt process memory or terminate the PHP process. Reaching this issue requires a non-default runtime configuration that permits multi-gigabyte values. No MongoDB server interaction is required.
CVE-2026-93765 High 2026-09-18 Not applicable No public exploit Mongoid contains an unsafe reflection weakness in the document persistence layer of its object-document mapping code. Input whose keys are passed through from an unauthenticated party by an embedding application can cause unintended internal method invocation instead of the intended array field update. This may result in unintended removal of stored records and in the embedding application becoming unresponsive.
CVE-2026-93764 High 2026-09-18 Not applicable No public exploit Mongoid may omit encryption rules for fields declared on embedded models when generating the client-side field-level encryption schema. Applications that enable this feature can therefore store values intended to be encrypted in readable form, with no error or warning. A party with routine read access to the database, a backup, or the underlying data files may then see data that was meant to remain unreadable outside the application.
CVE-2026-93763 High 2026-09-18 Not applicable No public exploit A protection mechanism failure in the object-document mapper's encryption configuration generation can cause fields that an application declared for client-side field-level encryption to be written and kept in cleartext, without any error or warning. A party holding ordinary read access to the database can then read values that were intended to be protected from that party. This may result in unintended disclosure of sensitive information.
CVE-2026-93762 Critical 2026-09-18 Not applicable No public exploit Mongoid contains an unsafe reflection weakness in the query path used for embedded documents. An application that passes an externally supplied field name to certain in-memory query methods may allow an unauthenticated party to obtain unintended disclosure of stored document data and to permanently remove stored records.
CVE-2026-93761 High 2026-09-18 Not applicable No public exploit An inefficient regular expression complexity issue in the in-memory query evaluation component of the Mongoid library may allow an unauthenticated party to cause excessive processing within an embedding application process. Applications that place user-supplied text into a pattern-matching query condition on an embedded association may become unresponsive.
CVE-2026-93760 High 2026-09-18 Not applicable No public exploit Mongoid does not restrict which query operators may come from caller-supplied filter data when an application hands that data to its query-building methods. In an application that forwards externally supplied filter parameters in this way, a party with no credentials may influence how the database evaluates the query. This may result in unintended disclosure of stored field values and in reduced database performance.
CVE-2026-93759 High 2026-09-18 Not applicable No public exploit Mongoid does not neutralize a string-typed query criterion supplied to its query builder, and instead passes it to the database as a server-side JavaScript expression. An unauthenticated party able to influence the value an application supplies as a query argument may cause code of their choosing to be evaluated by the database engine. This may result in unintended disclosure of stored field values, unintended selection of documents for application-initiated writes, and reduced database performance.
CVE-2026-93758 High 2026-09-18 Not applicable No public exploit An insecure direct object reference in the nested attributes handling of the Mongoid object-document mapper may allow a user with basic application privileges to reference a record identifier that is not their own. Processing such a request can cause that record to be looked up without the usual ownership or scoping restrictions, then updated and linked to the requesting user's own record. This may result in unintended disclosure and unauthorized modification of data belonging to other users of the application.
CVE-2026-93395 Medium 2026-09-17 Not applicable No public exploit A missing lower-bound validation in the bson_new_from_buffer() function of libbson allows an integer underflow when processing BSON data with a zero-length prefix. The function reads a 32-bit document length from the input buffer but does not verify that the value is at least 5 (the minimum valid BSON document size) before using it in an array index calculation. When the length field is zero, the expression used to check the document's null terminator wraps to UINT32_MAX, causing a heap out-of-bounds read that crashes the process. An unauthorized party who can supply crafted BSON input to an application using this API can cause a denial of service.
CVE-2026-93394 Medium 2026-09-17 Not applicable No public exploit A flaw in libmongoc's SCRAM authentication implementation caused the client to continue the authentication handshake and transmit the client proof even when a nonce mismatch was detected in the server's first message. An unauthorized party with a man-in-the-middle position could exploit this by injecting a crafted server-first-message containing a controlled salt and low iteration count, then capturing the resulting client proof to perform offline password cracking. This vulnerability is mitigated by TLS, which is standard in production deployments.
CVE-2026-93393 Critical 2026-09-17 Not applicable No public exploit A heap-based buffer overflow exists in the TLS transport layer of the MongoDB C Driver when built with the Windows platform TLS backend. A remote endpoint that the client connects to can cause the driver to write uncontrolled data outside the bounds of a heap allocation while processing incoming encrypted traffic after the TLS handshake completes. No authentication or user interaction is required, because the affected processing occurs before any application-level authentication completes. Triggering this issue may lead to memory corruption in the client process, disclosure of adjacent heap memory, or termination of the process.
CVE-2026-92758 Medium 2026-09-17 Not applicable No public exploit If logging mode is set to DEBUG or a malformed MongoDB connection string is used, application logs may collect sensitive information (if in use) such as passwords and AWS secure access keys.
CVE-2026-92757 Medium 2026-09-17 Not applicable No public exploit Applications built on MongoDB Entity Framework Core Provider which place a database name in the connection string may inadvertently disable field level encryption.
CVE-2026-92756 Medium 2026-09-17 Not applicable No public exploit Applications built on MongoDB Entity Framework Core Provider which combine independent encryption settings and this provider's encryption settings may silently lose TLS and schema-map settings leading to protected fields being stored unencrypted in the database.
CVE-2026-89099 High 2026-09-11 Not applicable No public exploit A race condition in the document value layer of MongoDB Server can allow concurrent server threads to operate on the same internal memory without synchronization, leading to memory corruption. An authenticated user holding ordinary read-write privileges on a database may be able to trigger this condition over the normal client protocol, resulting in server termination and potential corruption of process memory with user-influenced content. Successful use of this issue may impact the confidentiality, integrity, and availability of the affected server process.
CVE-2026-88036 Medium 2026-09-10 Not applicable No public exploit Improper neutralization of special elements in data query logic in the GridFS component of the MongoDB C Driver can cause a caller-supplied structured file identifier to be interpreted as a query condition rather than as a literal identifier. An authenticated user who can influence the identifier passed by an affected application may obtain stored file content beyond the intended target or cause all GridFS file chunks in the affected bucket to be removed, rendering stored file content unreadable.
CVE-2026-88035 Medium 2026-09-10 Not applicable No public exploit A size check in the client-side authentication path of the MongoDB C Driver can wrap around, so an unusually large user-name value is accepted and copied past the end of a small buffer. A party able to set the driver's connection settings may cause the application that embeds the driver to terminate unexpectedly. Reaching this code requires a build in which the optional external SASL authentication backend is present and a connection configured to use it.
CVE-2026-88034 Medium 2026-09-10 Not applicable No public exploit Improper neutralization of special elements in data query logic in the GridFS component of the MongoDB C++ Driver can cause a caller-supplied structured file identifier to be interpreted as a query condition rather than as a literal identifier. An authenticated user who can influence the identifier passed by an affected application may obtain stored file content beyond the intended target or cause all GridFS file chunks in the affected bucket to be removed, rendering stored file content unreadable.
CVE-2026-88033 Medium 2026-09-10 Not applicable No public exploit Improper neutralization of special elements in data query logic in the GridFS component of the MongoDB Java Driver can cause a caller-supplied structured file identifier to be interpreted as a query condition rather than as a literal identifier. An authenticated user who can influence the identifier passed by an affected application may obtain stored file content beyond the intended target or cause all GridFS file chunks in the affected bucket to be removed, rendering stored file content unreadable. The affected rename operation may also rename a stored file other than the intended target.
CVE-2026-88032 High 2026-09-10 Not applicable No public exploit A use-after-free in the reactive client-side encryption component of the MongoDB Java Driver can cause native resources to be freed while an affected encrypted operation is still using them when the operation is cancelled. A party able to cause such an operation to be cancelled may cause the hosting application process to terminate. Reaching the issue requires an affected reactive encryption configuration that retrieves KMS credentials on demand.
CVE-2026-88031 Medium 2026-09-10 Not applicable No public exploit Improper neutralization of special elements in data query logic in the GridFS component of the MongoDB Go Driver can cause a caller-supplied structured file identifier to be interpreted as a query condition rather than as a literal identifier. An authenticated user who can influence the identifier passed by an affected application may cause all GridFS file chunks in the affected bucket to be removed, rendering stored file content unreadable.
CVE-2026-88030 Medium 2026-09-10 Not applicable No public exploit Improper neutralization of special elements in data query logic in the GridFS component of the MongoDB Ruby Driver can cause a caller-supplied structured file identifier to be interpreted as a query condition rather than as a literal identifier. An authenticated user who can influence the identifier passed by an affected application may obtain stored file content beyond the intended target or cause all GridFS file chunks in the affected bucket to be removed, rendering stored file content unreadable.
CVE-2026-88029 Medium 2026-09-10 Not applicable No public exploit Improper neutralization of special elements in data query logic in the GridFS component of the MongoDB Python Driver can cause a caller-supplied structured file identifier to be interpreted as a query condition rather than as a literal identifier. An authenticated user who can influence the identifier passed by an affected application may obtain stored file content beyond the intended target or cause all GridFS file chunks in the affected bucket to be removed, rendering stored file content unreadable. The affected rename operation may also rename a stored file other than the intended target.
CVE-2026-88028 High 2026-09-10 Not applicable No public exploit Improper neutralization of special elements in data query logic in the polymorphic relation handling of the MongoDB integration for Laravel can cause a caller-supplied relation identifier to be interpreted as a query condition rather than as a literal identifier. An authenticated user who can influence a stored relation identifier may cause an affected application to return a document other than the intended relation target.
CVE-2026-88027 High 2026-09-10 Not applicable No public exploit Improper neutralization of special elements in data query logic in the embedded-document relation handling of the MongoDB integration for Laravel can cause a caller-supplied embedded record identifier to be interpreted as a query condition rather than as a literal identifier. An authenticated user who can influence such an identifier may delete all embedded documents in a targeted record or overwrite an embedded document other than the intended target.
CVE-2026-88026 High 2026-09-10 Not applicable No public exploit Improper neutralization of regular-expression metacharacters in the LINQ query translation component of the MongoDB C# Driver can cause a caller-supplied character sequence to alter a regular-expression predicate generated by an affected application. An authenticated user who can influence such a value may cause the application to return records beyond those intended by the original filter.
CVE-2026-88025 Medium 2026-09-10 Not applicable No public exploit Improper neutralization of special elements in data query logic in the GridFS component of the MongoDB C# Driver can cause a caller-supplied structured file identifier to be interpreted as a query condition rather than as a literal identifier. An authenticated user who can influence the identifier passed by an affected application may obtain stored file content beyond the intended target or cause all GridFS file chunks in the affected bucket to be removed, rendering stored file content unreadable. The affected rename operation may also rename a stored file other than the intended target.
CVE-2026-88024 Medium 2026-09-10 Not applicable No public exploit Improper neutralization of special elements in data query logic in the GridFS component of the MongoDB Rust Driver can cause a caller-supplied structured file identifier to be interpreted as a query condition rather than as a literal identifier. An authenticated user who can influence the identifier passed by an affected application may obtain stored file content beyond the intended target or cause all GridFS file chunks in the affected bucket to be removed, rendering stored file content unreadable.
CVE-2026-88023 Medium 2026-09-10 Not applicable No public exploit Improper neutralization of special elements in data query logic in the GridFS component of the MongoDB PHP Library can cause a caller-supplied structured file identifier to be interpreted as a query condition rather than as a literal identifier. An authenticated user who can influence the identifier passed by an affected application may obtain stored file content beyond the intended target or cause all GridFS file chunks in the affected bucket to be removed, rendering stored file content unreadable. The affected rename operation may also rename a stored file other than the intended target.
CVE-2026-88022 High 2026-09-10 Not applicable No public exploit Improper neutralization of special elements in data query logic in the MongoDB integration for Laravel can cause an array supplied to an explicit equality filter to be interpreted as a query condition rather than as a literal value. This affects the three-argument `where` method when the operator is `=` or `eq`, as well as the `find` and `delete` methods that use that code path. An attacker who can cause an affected application to supply an operator-shaped array to one of these APIs may obtain a document other than the intended target or delete documents beyond the intended target.
CVE-2026-82076 High 2026-09-08 Not applicable No public exploit An integer overflow in the query planning component of MongoDB Server can allow an authenticated user with ordinary database-level read/write privileges to bypass an internal resource limit. Submitting a specially crafted query causes the server to consume memory without bound during query planning, and the resulting exhaustion terminates the server process. This may result in a denial of service affecting all databases served by the affected node.
CVE-2026-82075 High 2026-09-08 Not applicable No public exploit An uncontrolled resource consumption weakness exists in the request-handling path of the MongoDB sharded-cluster router process. A client that has network access to a router port and has not authenticated can supply connection-monitoring parameters that cause the server to expend CPU resources without any rate limiting, degrading or denying service to legitimate clients. No authentication, elevated privileges, or user interaction is required. Only availability is affected; data confidentiality and integrity are not impacted.
CVE-2026-82074 High 2026-09-08 Not applicable No public exploit MongoDB Server contains an incorrect authorization vulnerability in the aggregation framework. An authenticated user with minimal privileges can craft a specially formatted aggregation request that causes the server's authorization subsystem to evaluate a different operation than what is actually executed, resulting in unauthorized read access to collection data within the target database.
CVE-2026-82073 High 2026-09-08 Not applicable No public exploit A security issue in the MongoDB Server aggregation framework allows an authenticated user with limited read privileges to bypass view-level authorization checks and access data from unauthorized collections when Atlas Search features are in use. The issue stems from insufficient validation of an internal command parameter that can be set by external clients, causing a security check to be improperly skipped.
CVE-2026-82071 High 2026-09-08 Not applicable No public exploit Insufficient validation of storage engine configuration options in MongoDB Server allows an authenticated user with write privileges to supply crafted parameters during collection creation that override internal storage metadata. This results in an out-of-bounds memory write in the server process, causing a denial of service via server crash, with potential for further impact including arbitrary code execution.
CVE-2026-82070 High 2026-09-08 Not applicable No public exploit A security issue in MongoDB Server's diagnostic reporting interface allows an authenticated user with monitoring privileges to access insufficiently protected credentials from concurrent administrative operations. The same credentials are properly redacted in server log output, but the diagnostic interface omits equivalent redaction. Successful exploitation requires a valid authenticated session with monitoring-level permissions and results in exposure of cleartext credentials that could enable impersonation of other users, including privileged accounts.
CVE-2026-82069 Medium 2026-09-08 Not applicable No public exploit A security issue in MongoDB Server's query statistics serialization on the router allows users with monitoring privileges to access unredacted search query text from other users' operations. An improper conditional check in the serialization logic causes the data redaction mechanism to be bypassed when processing search queries through the sharded cluster router. This results in sensitive query literals being stored and made accessible through the query statistics interface.
CVE-2026-82068 High 2026-09-08 Not applicable No public exploit A security issue in MongoDB Server allows an authenticated user with write privileges to trigger a persistent fatal assertion crash by sending specially crafted retryable write commands. The crash state is durably persisted, causing the server process to repeatedly crash on restart and potentially propagating to additional nodes in a sharded cluster. Manual intervention is required to restore service availability.
CVE-2026-82067 Critical 2026-09-08 Not applicable No public exploit Improper handling of case sensitivity in the configuration validation component of MongoDB Server may cause the authorization subsystem to remain in a default disabled state during server startup. An unauthenticated user with network access to a deployment where this condition occurs can perform arbitrary administrative operations, resulting in full impact of data confidentiality, integrity, and availability.
CVE-2026-82066 Medium 2026-09-08 Not applicable No public exploit A heap out-of-bounds read security issue exists in the query planning component of MongoDB Server. An authenticated user with database read and write privileges can trigger the security issue through crafted query operations, causing the server to read memory beyond allocated buffer boundaries. The revealed memory contents may be partially observable through diagnostic query statistics output.
CVE-2026-82065 High 2026-09-08 Not applicable No public exploit A security issue in the MongoDB Server's storage engine integration layer allows an authenticated user with collection creation privileges to cause a persistent denial of service. Insufficient validation of user-supplied storage configuration options permits values that, once persisted to durable metadata, trigger a fatal assertion failure when the metadata is subsequently read by diagnostic operations. The corrupted metadata persists across server restarts and is replicated to other cluster members, requiring manual operator intervention to restore service.
CVE-2026-82064 High 2026-09-08 Not applicable No public exploit A security issue in MongoDB Server allows an unauthenticated network user to cause a denial of service on a specific type of replica set member. The server contains an assertion in its read concern processing logic that can be reached without authentication, and the assertion's assumptions about internal state do not hold for all member configurations, causing the server process to terminate.
CVE-2026-82063 Medium 2026-09-08 Not applicable No public exploit A use-after-free security issue in the cursor management component of MongoDB Server allows an authenticated user to cause a denial of service. Under specific timing conditions during cursor operations, a stale pointer to a freed resource may be retained and subsequently dereferenced during cursor cleanup, leading to a server process crash.
CVE-2026-82062 High 2026-09-08 Not applicable No public exploit A security issue in MongoDB Server allows an authenticated user with elevated internal privileges to bypass a disabled feature gate in the applyOps command by specifying an internal replication mode value that was not intended to be client-selectable. This bypass enables execution of container operations that are disabled by default in production configurations, allowing direct storage-engine writes to arbitrary internal storage tables. The authorization check for these operations validates only the operation's namespace, not the actual storage target, enabling writes to unrelated internal metadata or other collections' data.
CVE-2026-82061 High 2026-09-08 Not applicable No public exploit A use-after-free security issue exists in the server's query execution memory tracking subsystem. An authenticated user with read privileges can trigger a write to freed heap memory through a sequence of standard database commands, leading to server process crash or potential memory corruption. No user interaction is required.
CVE-2026-82060 Low 2026-09-08 Not applicable No public exploit In MongoDB, insufficient validation of shard key values during document insertion allowed authenticated users to store documents with specially crafted, operator-shaped objects as shard key values in sharded collections. When change stream events for such documents were processed with the updateLookup full document mode, the crafted values were embedded into internal post-image lookup queries without proper sanitization, causing them to be interpreted as query operators rather than literal equality values. This could result in change stream consumers receiving incorrect post-image documents or encountering non-resumable fatal errors.
CVE-2026-82059 Medium 2026-09-08 Not applicable No public exploit An internal aggregation expression in MongoDB Server was incorrectly registered as accessible to any authenticated user rather than being restricted to internal cluster operations. By crafting a malformed index specification within this expression, an authenticated user with read-only privileges could trigger an assertion failure in the index key generation code path. In certain build configurations, this assertion failure results in termination of the mongod process, causing a denial of service to all connected clients.
CVE-2026-82058 High 2026-09-08 Not applicable No public exploit A flaw in MongoDB's JSON Schema validation error generation code allows an authenticated user with readWrite privileges to crash the mongod server. When a BSON document containing an array with a malformed numeric field name fails a $jsonSchema items type constraint, the error generation path performs unsafe numeric conversion on the user-controlled field name without proper exception handling, resulting in an uncaught exception that terminates the server process. This is possible because incoming wire protocol BSON validation does not enforce that array element field names are valid, in-range numeric indices.
CVE-2026-82057 High 2026-09-08 Not applicable No public exploit A security issue was discovered in MongoDB where an authenticated user with readWrite privileges could crash the mongod server process. By specifying a custom WiredTiger storage configuration option with an incompatible value during collection creation, a user could cause a type confusion in the storage engine layer. When documents were subsequently read from the misconfigured collection, the resulting mismatch in expected data format led to corrupted memory interpretation and a server crash. The crafted collection configuration persists across restarts, requiring manual operator intervention to remediate.
CVE-2026-82056 Medium 2026-09-08 Not applicable No public exploit A race condition in MongoDB server's text index query parsing can cause a heap use-after-free read when handling upsert retry paths. Under certain concurrent index lifecycle operations, a raw pointer to internal text index metadata may be dereferenced after the underlying structures have been freed, leading to a server crash. An authenticated user with readWrite privileges can trigger this condition through specific concurrent text-search and index management operations, resulting in denial of service for all connected clients. This
CVE-2026-82055 High 2026-09-08 Not applicable No public exploit A security issue exists in MongoDB's 2dsphere index key generation that can cause a server crash due to a null pointer dereference. When a specially crafted GeoJSON document is inserted into a collection with a 2dsphere index, an inconsistency in geometry parsing can leave an internal object in an invalid, partially initialized state. During subsequent index key generation, access to this improperly initialized object results in a null pointer dereference that terminates the mongod process. An authenticated user with write access can use this to cause a denial of service.
CVE-2026-82054 High 2026-09-08 Not applicable No public exploit A security issue exists in MongoDB server's JSON Pointer parser used during $jsonSchema query filter processing. When a find command includes a specially crafted $jsonSchema filter field, the parser processes the input without enforcing adequate limits on iteration count or total allocation size, resulting in significant memory amplification. Under concurrent request load, the cumulative memory consumption can exhaust available heap memory, causing the server's out-of-memory handler to terminate the mongod process and deny service to all connected clients.
CVE-2026-82053 High 2026-09-08 Not applicable No public exploit A security issue exists in MongoDB's LDAP authorization integration where pooled LDAP connections can retain stale authentication identities after user authentication under certain configurations. Subsequent authorization queries may execute under an unintended LDAP identity rather than the expected one. This can result in incorrect role assignments based on the LDAP directory's access control configuration, potentially allowing an authenticated user to acquire elevated privileges that were not intended by the deployment's authorization policy.
CVE-2026-82052 High 2026-09-08 Not applicable No public exploit The $regexFindAll expression can be used by an authenticated user who can run aggregation pipeline stages to crash a MongoDB server (mongod). Under certain specific conditions the  regex match can start in the middle of a multi-code-unit character, triggering an assertion during query execution.
CVE-2026-84971 High 2026-09-03 Not applicable No public exploit Improper handling of an unexpected value size in the decryption path of a client-side encryption library can cause a failed internal check that terminates the process using the library. A party able to place a suitably formed encrypted value where an application will decrypt it, or able to control the responses the application receives, may cause that application to stop running.
CVE-2026-84970 Medium 2026-09-03 Not applicable No public exploit A numeric truncation weakness exists in the JSON parsing component of the MongoDB C++ Driver's BSON library. An actor who controls the text that an embedding application hands to the library's public JSON parsing interface, when that text is very large, can cause the library to read memory beyond the supplied buffer and return it to the caller, to silently accept only part of the input as a complete document, or to terminate the process. No MongoDB server, credentials, or non-default configuration is required; the effect is confined to the process that uses the library.
CVE-2026-84969 Medium 2026-09-03 Not applicable No public exploit A memory-handling error in the BSON-to-JSON conversion helpers of the MongoDB C Driver can write a small number of bytes past the end of a heap buffer when a binary field is encoded and the output is cut short at a caller-configured length limit. A party who supplies the document content, with no privileges on the application that links the driver, may cause a small amount of data outside the intended buffer to be altered.
CVE-2026-84968 Medium 2026-09-03 Not applicable No public exploit An out-of-bounds read in the BSON decoding component of the MongoDB PHP driver may allow an unauthenticated party who supplies specially formed input to have a small amount of adjacent process memory copied into an error message that is returned to application code. This may result in unintended disclosure of limited memory contents.
CVE-2026-84967 Medium 2026-09-03 Not applicable No public exploit A component of the MongoDB extension for Visual Studio Code does not neutralize special characters in a connection string before that value is placed into a command line the extension composes for an integrated terminal. An unauthenticated remote unauthorized-user who persuades a developer to accept a user-supplied connection target, and then to open the extension's shell feature, can place characters of the unauthorized-user’s choosing into that command line. No privileges on the developer's machine are required, but several user actions are. The confirmation the developer sees does not display the supplied text.
CVE-2026-84966 Medium 2026-09-03 Not applicable No public exploit An incorrect numeric type conversion in the BSON document building component of the MongoDB C++ Driver may cause a length value to be interpreted incorrectly. When an application supplies an extremely large, non-terminated field name to the builder, the library may read memory outside the intended buffer and terminate the calling process. No authentication is required, but the calling application must pass the oversized name in a specific form.
CVE-2026-84965 Medium 2026-09-03 Not applicable No public exploit An integer wraparound in an allocation size calculation in the BSON library's JSON parsing code can cause a buffer to be released while a following copy operation still writes through the stale pointer. On builds where sizes are 32 bits, an unauthenticated party able to supply a sufficiently large JSON input to an application that links the library may cause that application to terminate unexpectedly, resulting in denial of service.
CVE-2026-84964 High 2026-09-03 Not applicable No public exploit A double free in the OpenSSL-based TLS certificate revocation checking path of the MongoDB C Driver can be reached by a TLS endpoint that the client already trusts. During the handshake, specially formed certificate data can cause the same heap object to be released twice. An unauthenticated party acting as the trusted endpoint may cause the connecting client application to terminate unexpectedly.
CVE-2026-84963 Medium 2026-09-03 Not applicable No public exploit An incorrect numeric conversion in the JSON parsing component of the MongoDB C Driver's BSON library may cause an unusually large text value to be silently shortened, or the corresponding field to be omitted, while the parsing operation still reports success and returns no error. An unauthenticated party who can supply the input processed by an application that uses this component may cause that application to hold data that does not match what was submitted, which may result in unintended alteration of data.
CVE-2026-84962 Medium 2026-09-03 Not applicable No public exploit An unauthorized user with key vault write access may cause an authorized client to issue arbitrary authenticated Google Cloud KMS API calls under the authorized user's identity, escalating database-level access into cloud key control and defeating client-side encryption.
CVE-2026-81533 Medium 2026-08-28 Not applicable No public exploit An application using the MongoDB BI Connector ODBC Driver may encounter a memory-safety issue when a submitted SQL statement contains an unusually long run of digits following a LIMIT clause. The issue occurs only on connections where the driver's optional prefetch setting is enabled, and stems from the driver copying the digit sequence into a fixed-size internal buffer without checking its length. A user able to influence the numeric portion of a LIMIT clause could cause the hosting application process to terminate unexpectedly or corrupt adjacent memory in that process.
CVE-2026-81532 High 2026-08-28 Not applicable No public exploit A user able to submit SQL through an application using the MongoDB Connector for BI ODBC driver can supply a positioned-cursor statement whose cursor name exceeds the size of an internal fixed-length buffer. Because the name length is not bounded before the driver builds its diagnostic message, memory adjacent to that buffer is overwritten with user-supplied content. This can terminate the hosting application process and may allow unintended code to run within it.
CVE-2026-81520 High 2026-08-28 Not applicable No public exploit A network-reachable client that has not yet authenticated can hold a MongoDB Connector for BI authentication session open indefinitely by beginning a SASL-based login exchange and then declining to complete it. Because the negotiation loop had no overall time bound and the read from the client had no deadline, each such session retains a worker, a client connection slot, and its associated backend database connections until the process is restarted. Repeated use of this behavior can consume the configured connection capacity and prevent legitimate users from establishing new sessions.
CVE-2026-81518 High 2026-08-28 Not applicable No public exploit When mongosqld is configured with a client certificate authority file, the listener requests a client certificate during the TLS handshake but does not require one, so a client that presents no certificate is still accepted. In deployments that rely on client certificates as the sole means of identifying users, a remote party with network access to the listener can therefore establish a session and read the MongoDB data exposed through the connector.
CVE-2026-81517 High 2026-08-28 Not applicable No public exploit An unauthenticated party able to reach the port of a MongoDB Connector for BI (mongosqld) instance may generate enough routine connection log activity to exhaust the storage backing the configured log path. When a log write or log rotation operation subsequently fails, the resulting error is not handled and the shared mongosqld process ends, ending service for all connected SQL clients. The process continues to end on startup until an operator restores available storage, and the diagnostic message explaining the condition is not recorded.
CVE-2026-81490 High 2026-08-28 Not applicable No public exploit A database user able to create a view in a namespace that MongoDB Connector for BI samples can cause the schema-sampling routine to stop functioning by defining a view whose evaluation reliably fails. The sampling logic classifies the resulting server message as transient and, after the configured retries are exhausted, proceeds without a valid result, ending the schema refresh routine. The mongosqld process continues running without a usable schema, so SQL clients are unable to obtain results until an operator removes the view or excludes its namespace from sampling.
CVE-2026-77586 High 2026-08-28 Not applicable No public exploit In MongoDB Connector for BI, MongoDB object names such as collection, field, and index names are placed into the quoted identifiers of the DDL text returned by SHOW CREATE statements without escaping the identifier delimiter. A user with permission to write to a sampled MongoDB collection can choose a name that closes the quoted identifier early, so that additional SQL text becomes part of the generated output. If an operator or automated tool later replays that generated statement against a SQL server, the additional text is executed with the privileges of that session.
CVE-2026-77184 Medium 2026-08-28 Not applicable No public exploit In MongoDB Connector for BI, the description text of a collection's JSON schema validator is incorporated into the comment text of the DDL returned by SHOW CREATE statements without complete escaping of backslash characters. A user with permission to modify a collection's schema validator, in deployments configured to build their SQL schema from those validators, can cause additional SQL text to be embedded in that generated output. If an operator or automated tool later replays that generated statement against a SQL server, the additional text is executed with the privileges of that session.
CVE-2026-76798 Medium 2026-08-28 Not applicable No public exploit The MongoSQL Transition Readiness Tool writes query text and user names read from BI Connector log files into its generated HTML report without encoding them for that output context. A user able to issue queries through the BI Connector can influence log content so that markup supplied in a query is interpreted by the browser when an operator later generates and opens the report, which may disclose other users' logged query text and user names to an external party or present misleading content to the operator. Generating a report over logs containing the affected entries and opening that report in a browser is required.
CVE-2026-76797 Medium 2026-08-28 Not applicable No public exploit The MongoSQL Transition Readiness Tool writes database and collection names into its generated CSV reports without neutralizing leading characters that spreadsheet applications treat as formulas. A user with write privileges on the cluster can choose a namespace name that is later evaluated as a formula when an operator opens the generated report in a spreadsheet application, which may result in unintended disclosure of report contents or execution of external content on the operator's workstation. Generating a report for the affected namespace and opening it in a spreadsheet application is required.
CVE-2026-76794 Medium 2026-08-28 Not applicable No public exploit MongoSQL Transition Readiness Tool does not sufficiently encode database metadata before including it in generated HTML. A MongoDB user with write access can introduce crafted metadata that may cause script code to run when another user generates and opens the report, potentially exposing report contents or altering its display.
CVE-2026-81530 Medium 2026-08-27 Not applicable No public exploit A weakness in the client-side encryption configuration surface of the MongoDB C# Driver causes sensitive key-management credential material supplied by the application to be reproduced verbatim in the driver's human-readable diagnostic representation of its client settings, instead of being masked as other secret fields are. A party able to read the application's logs, diagnostic output, or a process memory dump may thereby recover the plaintext credentials and use them to decrypt protected field data.
CVE-2026-81529 High 2026-08-27 Not applicable No public exploit Improper neutralization of delimiters in connection-URL construction allows connection-option injection in the MongoDB C# Driver. When an application passes untrusted text into the driver's connection-URL builder and round-trips the builder back into a client configuration, the untrusted text is serialized without neutralizing the URL/option delimiters and is then re-parsed as authoritative connection options. A low-privileged user of such an application can thereby introduce or suppress security-relevant connection settings.
CVE-2026-81528 Medium 2026-08-27 Not applicable No public exploit A MongoDB C# driver document-replacement code path omits the element-name/shape validation that the equivalent write paths apply, so a value supplied as a replacement is forwarded to the server without neutralization of query-language special elements. An application that passes untrusted, loosely-typed input as a replacement value therefore allows that input to be interpreted by the database as update logic rather than as data, executing under the application's own database credentials. Applications using strongly-typed document mappings are not affected.
CVE-2026-81527 Medium 2026-08-27 Not applicable No public exploit A NoSQL/expression injection weakness exists in the LINQ-to-aggregation query translation layer of the MongoDB C# Driver, in both aggregation expression and query filter translation. When application-supplied values are embedded in certain query constructs, special elements contained within those values are not properly escaped before the resulting query is transmitted to the database, so portions of the value may be interpreted by the database as query logic rather than as data. A user able to supply values that an application incorporates into an affected query may thereby cause unintended data to be returned or query results to be altered.
CVE-2026-81526 High 2026-08-27 Not applicable No public exploit The MongoDB Rust Driver does not neutralize special characters in a caller-supplied target identifier before embedding it in the request it sends to the server. An actor able to influence that identifier in an application using the driver may cause write operations to be applied to an unintended target within the same deployment using the application's own credentials. This may result in unauthorized modification of data belonging to another logical boundary enforced by the application.
CVE-2026-81525 High 2026-08-27 Not applicable No public exploit The MongoDB client library for PHP does not sufficiently sanitize special elements in application-supplied namespace identifiers before using them to construct the target namespace for database operations. An application that incorporates untrusted text into these identifiers may have operations silently directed at a different storage location than the one the application intended.
CVE-2026-81524 Medium 2026-08-27 Not applicable No public exploit A weakness in the MongoDB C Driver allows special elements in caller-supplied database and collection name components to pass without sanitization when the driver composes the target namespace for an operation. An application that incorporates untrusted input into these name components can have operations directed at a resource other than the one intended.
CVE-2026-81523 Low 2026-08-27 Not applicable No public exploit A missing input-validation issue in MongoDB libmongocrypt's automatic-encryption context setup allows a caller-supplied database identifier to be accepted without sanitization. The resulting impact is limited to incorrect schema selection, which may lead to limited disclosure or modification of information handled by the application.
CVE-2026-81522 High 2026-08-27 Not applicable No public exploit A weakness in the MongoDB C++ Driver's handling of caller-supplied namespace identifiers allows special characters embedded in those identifiers. An application that builds a namespace identifier from untrusted input without validating it may therefore have its operation directed at a different target than intended. This can result in limited unauthorized read and write access to data belonging to another logical tenant of the affected application.
CVE-2026-81521 High 2026-08-27 Not applicable No public exploit The MongoDB Go Driver's client-level bulk write operation may accept a caller-supplied database name containing a reserved separator character without escaping it before the name is used to build the target namespace for the operation. An application that passes untrusted input as a database name could therefore have the write directed at a database and collection other than the ones it intended. Only the Client.BulkWrite API is affected.
CVE-2026-75573 Medium 2026-08-27 Not applicable No public exploit In MongoDB Connector for BI, mongodrdl may write a TLS private-key password to standard error when the password is supplied through both the connection URI and the corresponding command-line option. A local user with access to the captured command output and encrypted key file may use the disclosed password to access the associated TLS client key.
CVE-2026-75159 High 2026-08-27 Not applicable No public exploit An unauthenticated client that can reach a MongoDB Connector for BI deployment configured with Kerberos authentication may cause mongosqld to terminate when a crafted authentication exchange encounters a specific GSSAPI error-handling condition. This can interrupt BI Connector availability until the process restarts.
CVE-2026-19503 Medium 2026-08-12 Not applicable No public exploit MongoDB Schema Manager and MongoDB Atlas SQL ODBC Driver do not validate the scheme of the authorization and token endpoints returned by an OIDC issuer's discovery document. A user induced to connect to an uncontrolled MongoDB deployment using MONGODB-OIDC authentication may have an uncontrolled URI dispatched to their operating system's default protocol handler, potentially exposing credentials or, under certain conditions, resulting in code execution in the user's context.
