| CVE | Severity | Published▾ | Status | Exploitation | Description |
|---|---|---|---|---|---|
| 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-2026-106433 | 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-2026-93765 | 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-2026-93761 | 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-2026-89099 | 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-2026-88032 | 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-2026-88028 | 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-2026-88022 | 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-2026-82068 | 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-2026-82065 | 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-2026-82062 | 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-2026-82058 | 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-2026-82055 | 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-2026-84964 | 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-2026-81532 | 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-2026-81529 | 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-2026-81526 | 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-2026-81522 | 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-2026-75159 | 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-2026-19004 | High | 2026-08-12 | Not applicable | No public exploit | An application using the MongoDB BI Connector ODBC Driver may experience a memory-safety issue when processing output parameters from a stored procedure. Triggering this issue requires connecting to an untrusted or impersonated database server that returns crafted metadata. This may result in process termination, disclosure of process memory, or, under certain conditions, arbitrary code execution. |
| CVE-2026-19003 | High | 2026-08-12 | Not applicable | No public exploit | A data source definition containing an over-length file path setting may cause the MongoDB BI Connector ODBC Driver setup dialog to write outside the bounds of an allocated buffer. The issue stems from an incorrect buffer capacity calculation in the dialog's file and folder selection handling, and is reached only when a user opens the setup dialog for such a data source and initiates a file or folder selection. Depending on build configuration, the result may range from abnormal process termination to, under certain conditions, execution of unintended code in the context of the user running the dialog. |
| CVE-2026-19002 | High | 2026-08-12 | Not applicable | No public exploit | A missing bounds check when parsing stored procedure parameter metadata in the MongoDB BI Connector ODBC Driver can result in an out-of-bounds write in the client application process. Triggering this issue requires control over the server the driver connects to, or the ability to respond in its place, in order to return malformed metadata. The resulting memory corruption may cause the client application to terminate abnormally or, under certain conditions, execute unintended code. |
| CVE-2026-18888 | High | 2026-08-12 | Not applicable | No public exploit | The MongoDB BI Connector ODBC Driver converts floating point column values into text without checking that the result fits within the destination buffer. When an application reads a sufficiently large floating point value as text, the driver may write beyond the end of that buffer and corrupt adjacent memory. A user who can store data in a collection read through the BI Connector could use this to crash the application performing the read. |
| CVE-2026-18712 | High | 2026-08-11 | Not applicable | No public exploit | An issue in MongoDB Server's Queryable Encryption maintenance operations could allow an authenticated user with privileges on one encrypted collection to cause unauthorized modification or destruction of data belonging to a different collection. This is due to insufficient validation of certain internal metadata references before they are used to perform operations on other namespaces. |
| CVE-2026-18711 | High | 2026-08-11 | Not applicable | No public exploit | An issue in MongoDB Server's query execution engine could allow an authenticated user with read and write privileges to cause an internal reference to be used after the underlying memory has been freed, when running certain queries against time-series collections. This could result in a server crash or disclosure of freed memory contents within query results. |
| CVE-2026-18710 | High | 2026-08-11 | Not applicable | No public exploit | A MongoDB driver component could write sensitive configuration information, including a credential used for outbound network connectivity, to application log output in cleartext during routine client initialization. This occurs automatically as part of normal operation and requires no special privileges to trigger. A party able to read the affected application's logs or downstream log-aggregation storage could recover the credential and reuse it to authenticate to the associated network infrastructure. This issue affects confidentiality only. |
| CVE-2026-18706 | High | 2026-08-11 | Not applicable | No public exploit | An issue in MongoDB Server's $graphLookup aggregation stage could allow an authenticated user able to issue aggregation and memory-management commands to cause an internal reference to be used after the underlying memory has been freed. This could result in a server crash or, potentially, execution of unintended code. |
| CVE-2026-18705 | High | 2026-08-11 | Not applicable | No public exploit | An issue in MongoDB Server's Atlas Vector Search feature could allow an authenticated user with read access to one view to retrieve documents from a different, protected view over the same underlying collection. This is due to insufficient handling of certain user-supplied fields when constructing an internal request forwarded to the search process. |
| CVE-2026-18704 | High | 2026-08-11 | Not applicable | No public exploit | An issue in MongoDB Server's aggregation framework could allow an authenticated user with only read privileges to perform write operations against collections they should not be able to modify. This is due to an internal-use aggregation stage being reachable by external clients without an appropriate authorization check on its embedded operations. |
| CVE-2026-18701 | High | 2026-08-11 | Not applicable | No public exploit | An issue in MongoDB Server's query subsystem could allow an authenticated user with read privileges to cause the server process to terminate unexpectedly by submitting a specially formed query filter. This could result in a denial of service. |
| CVE-2026-18697 | High | 2026-08-11 | Not applicable | No public exploit | An issue in MongoDB Server's aggregation framework could allow an unauthenticated party to cause a mongos (router) process to terminate unexpectedly by submitting a specially formed aggregation command. This could result in a denial of service, disrupting client connections routed through the affected mongos instance. |
| CVE-2026-18696 | High | 2026-08-11 | Not applicable | No public exploit | An issue in MongoDB Server's applyOps command could allow an authenticated user with specific non-default privileges to perform certain data-definition operations, such as dropping or modifying collections, against collections they do not have permission to manipulate. This is due to an inconsistency in how the target collection is determined between the authorization check and the actual operation. |
| CVE-2026-18695 | High | 2026-08-11 | Not applicable | No public exploit | An issue in MongoDB Server's handling of certain query predicates against time-series collections with a metaField could allow an authenticated user with write access to cause the server process to terminate unexpectedly, resulting in a denial of service. |
| CVE-2026-18694 | High | 2026-08-11 | Not applicable | No public exploit | An issue in MongoDB Server's geospatial query processing could allow an authenticated user with write privileges to cause certain malformed geometry data to be stored and later processed without proper validation. Subsequent queries against this data could then result in the server accessing memory outside its intended bounds. This could result in a server crash (denial of service) and may expose a limited amount of server process memory. |

| CVE-2026-13062 | High | 2026-07-22 | Not applicable | No public exploit | An authenticated user with write privileges on a Queryable Encryption-enabled collection may be able to modify internal encryption metadata fields that are intended to be server-controlled, by sending crafted write commands through the mongos router on a sharded cluster. This can result in corruption of encrypted query correctness. |
| CVE-2026-13060 | High | 2026-07-22 | Not applicable | No public exploit | An authenticated user with limited read privileges may be able to access documents from collections they are not authorized to read, due to an inconsistency in how the $graphLookup aggregation stage is evaluated during authorization and during execution. Affected scenarios involve collections referenced within existing view pipeline definitions. |
| CVE-2026-13059 | High | 2026-07-22 | Not applicable | No public exploit | An authenticated user with low privileges may be able to perform unauthorized reads and writes on data protected by role-based query-level access controls, due to insufficient validation of certain client-supplied command parameters. The issue affects find, update, delete, and aggregate commands in non-apiStrict configurations. |
| CVE-2026-13058 | High | 2026-07-22 | Not applicable | No public exploit | An authenticated user with basic write privileges can cause the mongod process to terminate abnormally by sending a crafted transaction command with an incomplete set of required fields. The issue stems from inconsistent validation across related transaction command parameters, resulting in a fatal internal invariant failure and denial of service. |
| CVE-2026-13056 | High | 2026-07-22 | Not applicable | No public exploit | Using expressions that generate large arrays it is possible to craft a query that creates very large intermediate objects in memory, causing the server to crash with OOM error. |
| CVE-2026-13055 | High | 2026-07-22 | Not applicable | No public exploit | The `$_internalIndexKey` aggregation expression can be used by any authenticated user to crash a MongoDB server (mongod). The expression fails to handle compound wildcard index specifications, triggering an internal consistency check that aborts the server process. The user must be able to run an aggregation pipeline. |
| CVE-2026-11933 | High | 2026-06-12 | Not applicable | No public exploit | A use-after-free vulnerability exists in MongoDB Server's server-side JavaScript engine when converting BSON documents to JavaScript arrays. An authenticated user with read privileges who is able to run server-side JavaScript (for example, via $where or $function) can cause the server to access memory that has already been freed. This may result in disclosure of information from the mongod process memory or a denial of service through a server crash. |
| CVE-2026-9754 | High | 2026-06-09 | Not applicable | No public exploit | An authenticated user with the read role may read limited amounts of uninitialized stack memory via specially-crafted issuances of the filemd5 command |
| CVE-2026-9753 | High | 2026-06-09 | Not applicable | No public exploit | The $_internalApplyOplogUpdate aggregation pipeline stage can be used to execute a document diff containing a malformed binary diff to return memory out-of-bounds or crash the server. $_internalApplyOplogUpdate can be executed by any authenticated user with access to the aggregate command. |
| CVE-2026-9752 | High | 2026-06-09 | Not applicable | No public exploit | An authorized user could trigger a server crash by running a query with a 2dsphere index on a field that stores a GeoJSON GeometryCollection containing a Polygon with a strict-winding CRS. Strict-winding polygons are intentionally unsupported for indexing, but the guard that rejects them does not inspect members of a GeometryCollection, allowing the unsafe path to be reached which ends with an ensuing null-pointer dereference. |
| CVE-2026-9750 | High | 2026-06-09 | Not applicable | No public exploit | An authenticated user can cause a MongoDB server to crash or return incorrect results by creating documents that interfere with internal metadata processing during query execution. This stems from insufficient separation between user-controlled document fields and internal metadata in certain execution paths. |
| CVE-2026-9749 | High | 2026-06-09 | Not applicable | No public exploit | This issue can occur when running an aggregation pipeline that uses the internal $exchange stage configured with key-range partitioning and order-preserving delivery. If a single key range produces enough documents to fill its exchange buffer (that is, many results are routed to the same consumer), the server reaches the code path where a full per-consumer buffer is detected but the internal "high watermark" for that key range is not updated as intended. |
| CVE-2026-9748 | High | 2026-06-09 | Not applicable | No public exploit | The $_internalConvertBucketIndexStats stage used PauseExecution as a way to signal "skip this document" when an index stats conversion failed. But PauseExecution is not a general purpose skip mechanism, but rather a TeeBuffer-internal signal used solely by $facet to coordinate its sub-pipelines. When this stage is placed before $facet in a pipeline, TeeBuffer receives the unexpected PauseExecution from upstream and hits a hard invariant assertion, crashing mongod. |
| CVE-2026-9747 | High | 2026-06-09 | Not applicable | No public exploit | Adding fromRouter:true and runtimeConstants.userRoles could cause aggregations to crash mongodb server. |
| CVE-2026-9746 | High | 2026-06-09 | Not applicable | No public exploit | When using $changestreams and $_requestReshardingResumeToken with the exchange option the server hits an invariant which causes the server to crash. There are no special privileges needed. The user must be logged in to issue the statement. |
| CVE-2026-9743 | High | 2026-06-09 | Not applicable | No public exploit | In MongoDB Server 8.0, an aggregation stage can leave its _subPipeline field null during processing of certain pipelines. If a getMore is subsequently issued on the same cursor, the server may dereference this null sub-pipeline when reattaching to the operation context, accessing an invalid address and crashing the process. This issue allows an authenticated user who can run aggregation pipelines to cause a denial of service by issuing a specially crafted aggregation followed by getMore on affected versions. |
| CVE-2026-9742 | High | 2026-06-09 | Not applicable | No public exploit | When OIDC authentication is enabled in configuration, clients may set specific values in the "mechanism" parameter of the "authenticate" command that lead to server crash. The authenticate command is accessible to unauthenticated clients, leading to pre-auth denial-of-service in affected product configurations. |
| CVE-2026-9741 | High | 2026-06-09 | Not applicable | No public exploit | A bug in query analysis processing of the $vectorSearch aggregation stage for Queryable Encryption (QE) or Client-Side Field Level Encryption (CSFLE) results in literal values for encrypted fields within the $vectorSearch stage filter expressions to be sent to the server as plaintext instead of ciphertext. |
| CVE-2026-9740 | High | 2026-06-09 | Not applicable | No public exploit | A vulnerability in MongoDB Server's BSON validation logic allows an unauthenticated user to crash the mongod process by sending a specially crafted message. The BSON validator's handling of certain nested binary data structures permits uncontrolled mutual recursion between validation functions, where each re-entry resets internal depth tracking. |
| CVE-2026-8843 | High | 2026-05-18 | Not applicable | No public exploit | Creating a "2dsphere_bucket" index on a non-timeseries bucket collection will succeed, but any subsequent attempt to insert a document which triggers updating that index will crash the server. A similar issue occurs when creating "queryable_encrypted_range" indices. This issue affects MongoDB Server v7.0 versions prior to 7.0.32, v8.0 versions prior to 8.0.21 and v8.2 versions prior to 8.2.6 |
| CVE-2026-8336 | High | 2026-05-13 | Not applicable | No public exploit | After invoking $_internalJsEmit, which is not intended to be directly accessible, or mapreduce command’s map function in a certain way, an authenticated user can subsequently crash mongod when the server-side JavaScript engine (through $where, $function, mapreduce reduce stage, etc.) is used also in a specific way, resulting in a post-authentication denial-of-service. This issue impacts MongoDB Server v8.2 versions prior to 8.2.9 and v8.3 versions prior to 8.3.2. |
| CVE-2026-8199 | High | 2026-05-13 | Not applicable | No public exploit | An authenticated user can cause excess memory usage via bitwise match expression AST processing of $bitsAllSet, $bitsAnySet, $bitsAllClear, and $bitsAnyClear. This contributes to memory pressure and may lead to availability loss by OOM. This issue impacts MongoDB Server v7.0 versions prior to 7.0.34, v8.0 versions prior to 8.0.23, v8.2 versions prior to 8.2.9 and v8.3 versions prior to 8.3.2. |
