CVE-2026-61487	Medium	2026-07-28	No exploit published	No public exploit	Improper Authorization vulnerability in Apache ActiveMQ Broker, Apache ActiveMQ All, Apache ActiveMQ. An authenticated low-privilege user can bypass a per-destination write ACL by sending to an ActiveMQ temporary composite destination whose physical name is a comma-separated composite of real queues. This allows publishing messages to any of the destinations in the list without proper write ACL permissions because the authorization check is bypassed due to the composite destination being marked as temporary. This issue affects Apache ActiveMQ Broker: before 5.19.9, from 6.0.0 before 6.2.8; Apache ActiveMQ All: before 5.19.9, from 6.0.0 before 6.2.8; Apache ActiveMQ: before 5.19.9, from 6.0.0 before 6.2.8.

CVE-2026-52760	Medium	2026-06-30	No exploit published	No public exploit	Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Apache ActiveMQ, Apache ActiveMQ Web Console. The browse page in the web console renders a message Id directly without sanitization. This allows an authenticated producer to send a message with a JMS message ID that has been crafted to contain HTML/JavaScript such that when an administrator browses the queue in the Web Console, the payload executes in their browser. This issue affects Apache ActiveMQ: before 5.19.8, from 6.0.0 before 6.2.7; Apache ActiveMQ Web Console: before 5.19.8, from 6.0.0 before 6.2.7. Users are recommended to upgrade to version 6.2.7 or 5.19.8, which fixes the issue.
CVE-2026-50750	High	2026-06-30	No exploit published	No public exploit	Denial of Service via Out of Memory vulnerability in Apache ActiveMQ Broker, Apache ActiveMQ, Apache ActiveMQ All. Following the fix for CVE-2026-49270 an unauthenticated attacker can now cause broker OOM by sending an repeated BrokerInfo commands without sending a ConnectionInfo, until the broker will crash with OOM. This issue affects Apache ActiveMQ Broker: from 5.19.7 before 5.19.8, from 6.2.6 before 6.2.7; Apache ActiveMQ: from 5.19.7 before 5.19.8, from 6.2.6 before 6.2.7; Apache ActiveMQ All: from 5.19.7 before 5.19.8, from 6.2.6 before 6.2.7.

CVE-2026-50734	High	2026-06-30	No exploit published	No public exploit	Memory Allocation with Excessive Size Value vulnerability in Apache ActiveMQ Client, Apache ActiveMQ, Apache ActiveMQ All. An unauthenticated network attacker can cause a broker DoS by sending a crafted WireFormatInfo frame with a malicious large size value. The value is not validate and causes the broker to attempt allocation during pre-auth negotiation which can trigger OOM and crash the broker. This issue affects Apache ActiveMQ Client: before 5.19.8, from 6.0.0 before 6.2.7; Apache ActiveMQ: before 5.19.8, from 6.0.0 before 6.2.7; Apache ActiveMQ All: before 5.19.8, from 6.0.0 before 6.2.7. Users are recommended to upgrade to version 6.2.7 or 5.19.8, which fixes the issue.
CVE-2026-49877	High	2026-06-30	No exploit published	No public exploit	Improper Authorization vulnerability in Apache ActiveMQ. An authenticated low-privilege Web Console user by default can access /admin/* paths in the Web Console. The default Jetty settings incorrectly did not limit those paths to only admins. This issue affects Apache ActiveMQ: before 5.19.8, from 6.0.0 before 6.2.7. Users are recommended to upgrade to version 6.2.7 or 5.19.8, which fixes the issue.
CVE-2026-49434	High	2026-06-30	No exploit published	No public exploit	Improper Input Validation vulnerability in Apache ActiveMQ Broker, Apache ActiveMQ, Apache ActiveMQ All. An attacker that has access to publish or modify entries in LDAP that match the configured searchBase and searchFilter can instantiate denied transports inside the broker JVM. This can be used to fetch an attacker URL and spawn a second BrokerService inside the same JVM. This issue affects Apache ActiveMQ Broker: before 5.19.8, from 6.0.0 before 6.2.7; Apache ActiveMQ: before 5.19.8, from 6.0.0 before 6.2.7; Apache ActiveMQ All: before 5.19.8, from 6.0.0 before 6.2.7.

CVE-2026-49432	High	2026-06-30	No exploit published	No public exploit	Improper Input Validation vulnerability in Apache ActiveMQ, Apache ActiveMQ All, Apache ActiveMQ Stomp. A remote unauthenticated peer that can reach an exposed STOMP connector can trigger denial-of-service behavior by sending a negative content-length. For the NIO STOMP transport, an attacker can keep streaming body bytes and grow the per-connection command buffer beyond configured limits to cause OOM. For the blocking STOMP protocol, an error will instead force abnormal transport exception handling for the affected connection and closure. This issue affects Apache ActiveMQ: before 5.19.8, from 6.0.0 before 6.2.7; Apache ActiveMQ All: before 5.19.8, from 6.0.0 before 6.2.7; Apache ActiveMQ Stomp: before 5.19.8, from 6.0.0 before 6.2.7.

CVE-2026-49270	Medium	2026-06-01	No exploit published	No public exploit	Exposure of Sensitive Information Through Metadata vulnerability in Apache ActiveMQ Broker, Apache ActiveMQ, Apache ActiveMQ All. Brokers that are configured with a network connector with syncDurableSubs set to true, are vulnerable to an unauthenticated attacker who can receive a list of all durable topic subscriptions in the broker, including client identifiers, subscription names, topic destinations, and JMS selector expressions, by sending a BrokerInfo command. The broker incorrectly responds without first ensuring the connection is authenticated. This issue affects Apache ActiveMQ Broker: before 5.19.7, from 6.0.0 before 6.2.6; Apache ActiveMQ: before 5.19.7, from 6.0.0 before 6.2.6; Apache ActiveMQ All: before 5.19.7, from 6.0.0 before 6.2.6. Users are recommended to upgrade to version 6.2.6 or 5.19.7, which fixes the issue.
CVE-2026-49157	High	2026-06-01	No exploit published	No public exploit	Incorrect Default Permissions vulnerability in Apache ActiveMQ. This issue affects Apache ActiveMQ: before 5.19.7, from 6.0.0 before 6.2.6. The default Jolokia authorization settings granted non-admin (low-privilege) web-login accounts access to Jolokia operations which allowed executing broker management operations meant for admins such as addQueue and removeQueue. Users are recommended to upgrade to version 6.2.6 or 5.19.7, which fixes the issue.
CVE-2026-46605	Medium	2026-06-01	No exploit published	No public exploit	Incomplete authorization by Apache ActiveMQ server before versions v6.2.6 and v5.19.7 allows authenticated connections to remove existing destinations with proper permissions. This issue affects Apache ActiveMQ Broker: before 5.19.7, from 6.0.0 before 6.2.6; Apache ActiveMQ All: before 5.19.7, from 6.0.0 before 6.2.6; Apache ActiveMQ: before 5.19.7, from 6.0.0 before 6.2.6. Users are recommended to upgrade to version v6.2.6 or v5.19.7, which fixes the issue.
CVE-2026-45505	High	2026-06-01	No exploit published	No public exploit	Improper Input Validation, Improper Control of Generation of Code ('Code Injection') vulnerability in Apache ActiveMQ Broker, Apache ActiveMQ All, Apache ActiveMQ. Non-parenthesized discovery wrappers such as `masterslave:vm://...,...` and `static:vm://...` incorrectly pass validation allowing bypass of fix in CVE-2026-34197. Original description from CVE-2026-34197. Apache ActiveMQ exposes the Jolokia JMX-HTTP bridge at /api/jolokia/ on the web console. The default Jolokia access policy permits exec operations on all ActiveMQ MBeans (org.apache.activemq:*), including BrokerService.addNetworkConnector(String) and BrokerService.addConnector(String). An authenticated attacker can invoke these operations with a crafted discovery UR that triggers the VM transport's brokerConfig parameter to load a remote Spring XML application context using ResourceXmlApplicationContext. Because Spring's ResourceXmlApplicationContext instantiates all singleton beans before the BrokerService validates the configuration, arbitrary code execution occurs on the broker's JVM through bean factory methods such as Runtime.exec(). This issue affects Apache ActiveMQ Broker: before 5.19.7, from 6.0.0 before 6.2.6; Apache ActiveMQ All: before 5.19.7, from 6.0.0 before 6.2.6; Apache ActiveMQ: before 5.19.7, from 6.0.0 before 6.2.6. Users are recommended to upgrade to version 5.19.7 or 6.2.6, which fixes the issue.
CVE-2026-42253	Medium	2026-06-01	No exploit published	No public exploit	Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Apache ActiveMQ, Apache ActiveMQ Web. The MessageServlet in the ActiveMQ web console API copies every JMS message property into an HTTP response header without any validation. This can allow overwriting and injecting security headers by setting them on JMS messages that are returned by the servlet. This issue affects Apache ActiveMQ: before 5.19.7, from 6.0.0 before 6.2.6; Apache ActiveMQ Web: before 5.19.7, from 6.0.0 before 6.2.6. Users are recommended to upgrade to version 5.19.7 or 6.2.6, which fixes the issue. The MessageServlet has now been deprecated and disabled by default.
CVE-2026-41044	High	2026-04-24	No exploit published	No public exploit	Improper Input Validation, Improper Control of Generation of Code ('Code Injection') vulnerability in Apache ActiveMQ, Apache ActiveMQ Broker, Apache ActiveMQ All. An authenticated attacker can use the admin web console page to construct a malicious broker name that bypasses name validation to include an xbean binding that can be later used by a VM transport to load a remote Spring XML application. The attacker can then use the DestinationView mbean to send a message to trigger a VM transport creation that will reference this malicious broker name which can lead to loading the malicious Spring XML context file. Because Spring's ResourceXmlApplicationContext instantiates all singleton beans before the BrokerService validates the configuration, arbitrary code execution occurs on the broker's JVM through bean factory methods such as Runtime.exec(). This issue affects Apache ActiveMQ: before 5.19.6, from 6.0.0 before 6.2.5; Apache ActiveMQ Broker: before 5.19.6, from 6.0.0 before 6.2.5; Apache ActiveMQ All: before 5.19.6, from 6.0.0 before 6.2.5. Users are recommended to upgrade to version 6.2.5 or 5.19.6, which fixes the issue.
CVE-2026-41043	Medium	2026-04-24	No exploit published	No public exploit	Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS) vulnerability in Apache ActiveMQ, Apache ActiveMQ Web. An authenticated attacker can show malicious content when browsing queues in the web console by overriding the content type to be HTML (instead of XML) and by injecting HTML into a JMS selector field. This issue affects Apache ActiveMQ: before 5.19.6, from 6.0.0 before 6.2.5; Apache ActiveMQ Web: before 5.19.6, from 6.0.0 before 6.2.5. Users are recommended to upgrade to version 6.2.5 or 5.19.6, which fixes the issue.
CVE-2026-39304	High	2026-04-10	No exploit published	No public exploit	Denial of Service via Out of Memory vulnerability in Apache ActiveMQ Client, Apache ActiveMQ Broker, Apache ActiveMQ. ActiveMQ NIO SSL transports do not correctly handle TLSv1.3 handshake KeyUpdates triggered by clients. This makes it possible for a client to rapidly trigger updates which causes the broker to exhaust all its memory in the SSL engine leading to DoS. Note: TLS versions before TLSv1.3 (such as TLSv1.2) are broken but are not vulnerable to OOM. Previous TLS versions require a full handshake renegotiation which causes a connection to hang but not OOM. This is fixed as well. This issue affects Apache ActiveMQ Client: before 5.19.4, from 6.0.0 before 6.2.4; Apache ActiveMQ Broker: before 5.19.4, from 6.0.0 before 6.2.4; Apache ActiveMQ: before 5.19.4, from 6.0.0 before 6.2.4. Users are recommended to upgrade to version 6.2.4 or 5.19.5, which fixes the issue.
CVE-2026-40046	High	2026-04-09	No exploit published	No public exploit	Integer Overflow or Wraparound vulnerability in Apache ActiveMQ, Apache ActiveMQ All, Apache ActiveMQ MQTT. The fix for "CVE-2025-66168: MQTT control packet remaining length field is not properly validated" was only applied to 5.19.2 (and future 5.19.x) releases but was missed for all 6.0.0+ versions. This issue affects Apache ActiveMQ: from 6.0.0 before 6.2.4; Apache ActiveMQ All: from 6.0.0 before 6.2.4; Apache ActiveMQ MQTT: from 6.0.0 before 6.2.4. Users are recommended to upgrade to version 6.2.4 or a 5.19.x version starting with 5.19.2 or later (currently latest is 5.19.5), which fixes the issue.
CVE-2026-32642	Low	2026-03-24	No exploit published	No public exploit	Incorrect Authorization (CWE-863) vulnerability in Apache Artemis, Apache ActiveMQ Artemis exists when an application using the OpenWire protocol attempts to create a non-durable JMS topic subscription on an address that doesn't exist with an authenticated user which has the "createDurableQueue" permission but does not have the "createAddress" permission and address auto-creation is disabled. In this circumstance, a temporary address will be created whereas the attempt to create the non-durable subscription should instead fail since the user is not authorized to create the corresponding address. When the OpenWire connection is closed the address is removed. This issue affects Apache Artemis: from 2.50.0 through 2.52.0; Apache ActiveMQ Artemis: from 2.0.0 through 2.44.0. Users are recommended to upgrade to version 2.53.0, which fixes the issue.
CVE-2026-27446	Critical	2026-03-04	No exploit published	No public exploit	Missing Authentication for Critical Function (CWE-306) vulnerability in Apache Artemis, Apache ActiveMQ Artemis. An unauthenticated remote attacker can use the Core protocol to force a target broker to establish an outbound Core federation connection to an attacker-controlled rogue broker. This could potentially result in message injection into any queue and/or message exfiltration from any queue via the rogue broker. This impacts environments that allow both: - incoming Core protocol connections from untrusted sources to the broker - outgoing Core protocol connections from the broker to untrusted targets This issue affects: - Apache Artemis from 2.50.0 through 2.51.0 - Apache ActiveMQ Artemis from 2.11.0 through 2.44.0. Users are recommended to upgrade to Apache Artemis version 2.52.0, which fixes the issue. The issue can be mitigated by one of the following: - Remove Core protocol support from any acceptor receiving connections from untrusted sources. Incoming Core protocol connections are supported by default via the "artemis" acceptor listening on port 61616. See the "protocols" URL parameter configured for the acceptor. An acceptor URL without this parameter supports all protocols by default, including Core. - Use two-way SSL (i.e. certificate-based authentication) in order to force every client to present the proper SSL certificate when establishing a connection before any message protocol handshake is attempted. This will prevent unauthenticated exploitation of this vulnerability. - Implement and deploy a Core interceptor to deny all Core downstream federation connect packets. Such packets have a type of (int) -16 or (byte) 0xfffffff0. Documentation for interceptors is available at https://artemis.apache.org/components/artemis/documentation/latest/intercepting-operations.html .
CVE-2025-66168	High	2026-03-04	No exploit published	No public exploit	WARNING: Users of 6.x should upgrade to 6.2.4 or later as the fix was missed in previous 6.x releases. See the following for more details: https://activemq.apache.org/security-advisories.data/CVE-2026-40046-announcement.txt https://www.cve.org/CVERecord?id=CVE-2026-40046 Original Report: Apache ActiveMQ does not properly validate the remaining length field which may lead to an overflow during the decoding of malformed packets. When this integer overflow occurs, ActiveMQ may incorrectly compute the total Remaining Length and subsequently misinterpret the payload as multiple MQTT control packets which makes the broker susceptible to unexpected behavior when interacting with non-compliant clients. This behavior violates the MQTT v3.1.1 specification, which restricts Remaining Length to a maximum of 4 bytes. The scenario occurs on established connections after the authentication process. Brokers that are not enabling mqtt transport connectors are not impacted. This issue affects Apache ActiveMQ: before 5.19.2, 6.0.0 to 6.1.8, and 6.2.0 Users are recommended to upgrade to version 5.19.2, 6.1.9, or 6.2.1, which fixes the issue.
CVE-2025-27391	Medium	2025-04-09	No exploit published	No public exploit	Insertion of Sensitive Information into Log File vulnerability in Apache ActiveMQ Artemis. All the values of the broker properties are logged when the org.apache.activemq.artemis.core.config.impl.ConfigurationImpl logger has the debug level enabled. This issue affects Apache ActiveMQ Artemis: from 1.5.1 before 2.40.0. It can be mitigated by restricting log access to only trusted users. Users are recommended to upgrade to version 2.40.0, which fixes the issue.
CVE-2025-27427	Low	2025-04-01	No exploit published	No public exploit	A vulnerability exists in Apache ActiveMQ Artemis whereby a user with the createDurableQueue or createNonDurableQueue permission on an address can augment the routing-type supported by that address even if said user doesn't have the createAddress permission for that particular address. When combined with the send permission and automatic queue creation a user could successfully send a message with a routing-type not supported by the address when that message should actually be rejected on the basis that the user doesn't have permission to change the routing-type of the address. This issue affects Apache ActiveMQ Artemis from 2.0.0 through 2.39.0. Users are recommended to upgrade to version 2.40.0 which fixes the issue.
CVE-2023-50780	High	2024-10-14	No exploit published	No public exploit	Apache ActiveMQ Artemis allows access to diagnostic information and controls through MBeans, which are also exposed through the authenticated Jolokia endpoint. Before version 2.29.0, this also included the Log4J2 MBean. This MBean is not meant for exposure to non-administrative users. This could eventually allow an authenticated attacker to write arbitrary files to the filesystem and indirectly achieve RCE. Users are recommended to upgrade to version 2.29.0 or later, which fixes the issue.
CVE-2021-4040	Medium	2022-08-24	No exploit published	No public exploit	A flaw was found in AMQ Broker. This issue can cause a partial interruption to the availability of AMQ Broker via an Out of memory (OOM) condition. This flaw allows an attacker to partially disrupt availability to the broker through a sustained attack of maliciously crafted messages. The highest threat from this vulnerability is system availability.
CVE-2021-21349	High	2021-03-23	No exploit published	No public exploit	XStream is a Java library to serialize objects to XML and back again. In XStream before version 1.4.16, there is a vulnerability which may allow a remote attacker to request data from internal resources that are not publicly available only by manipulating the processed input stream. No user is affected, who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types. If you rely on XStream's default blacklist of the Security Framework, you will have to use at least version 1.4.16.
CVE-2021-21348	High	2021-03-23	No exploit published	No public exploit	XStream is a Java library to serialize objects to XML and back again. In XStream before version 1.4.16, there is a vulnerability which may allow a remote attacker to occupy a thread that consumes maximum CPU time and will never return. No user is affected, who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types. If you rely on XStream's default blacklist of the Security Framework, you will have to use at least version 1.4.16.
CVE-2021-21343	High	2021-03-23	No exploit published	No public exploit	XStream is a Java library to serialize objects to XML and back again. In XStream before version 1.4.16, there is a vulnerability where the processed stream at unmarshalling time contains type information to recreate the formerly written objects. XStream creates therefore new instances based on these type information. An attacker can manipulate the processed input stream and replace or inject objects, that result in the deletion of a file on the local host. No user is affected, who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types. If you rely on XStream's default blacklist of the Security Framework, you will have to use at least version 1.4.16.
CVE-2021-26118	High	2021-01-27	No exploit published	No public exploit	While investigating ARTEMIS-2964 it was found that the creation of advisory messages in the OpenWire protocol head of Apache ActiveMQ Artemis 2.15.0 bypassed policy based access control for the entire session. Production of advisory messages was not subject to access control in error.
CVE-2021-26117	High	2021-01-27	No exploit published	No public exploit	The optional ActiveMQ LDAP login module can be configured to use anonymous access to the LDAP server. In this case, for Apache ActiveMQ Artemis prior to version 2.16.0 and Apache ActiveMQ prior to versions 5.16.1 and 5.15.14, the anonymous context is used to verify a valid users password in error, resulting in no check on the password.
CVE-2020-13920	Medium	2020-09-10	No exploit published	No public exploit	Apache ActiveMQ uses LocateRegistry.createRegistry() to create the JMX RMI registry and binds the server to the "jmxrmi" entry. It is possible to connect to the registry without authentication and call the rebind method to rebind jmxrmi to something else. If an attacker creates another server to proxy the original, and bound that, he effectively becomes a man in the middle and is able to intercept the credentials when an user connects. Upgrade to Apache ActiveMQ 5.15.12.
CVE-2020-13932	Medium	2020-07-20	No exploit published	No public exploit	In Apache ActiveMQ Artemis 2.5.0 to 2.13.0, a specially crafted MQTT packet which has an XSS payload as client-id or topic name can exploit this vulnerability. The XSS payload is being injected into the admin console's browser. The XSS payload is triggered in the diagram plugin; queue node and the info section.
CVE-2020-10727	Medium	2020-06-26	No exploit published	No public exploit	A flaw was found in ActiveMQ Artemis management API from version 2.7.0 up until 2.12.0, where a user inadvertently stores passwords in plaintext in the Artemis shadow file (etc/artemis-users.properties file) when executing the `resetUsers` operation.

Improper Input Validation, Improper Control of Generation of Code ('Code Injection') vulnerability in Apache ActiveMQ Broker, Apache ActiveMQ All, Apache ActiveMQ. Non-parenthesized discovery wrappers such as `masterslave:vm://...,...` and `static:vm://...` incorrectly pass validation allowing bypass of fix in CVE-2026-34197. Original description from CVE-2026-34197. Apache ActiveMQ exposes the Jolokia JMX-HTTP bridge at /api/jolokia/ on the web console. The default Jolokia access policy permits exec operations on all ActiveMQ MBeans (org.apache.activemq:*), including BrokerService.addNetworkConnector(String) and BrokerService.addConnector(String). An authenticated attacker can invoke these operations with a crafted discovery UR that triggers the VM transport's brokerConfig parameter to load a remote Spring XML application context using ResourceXmlApplicationContext. Because Spring's ResourceXmlApplicationContext instantiates all singleton beans before the BrokerService validates the configuration, arbitrary code execution occurs on the broker's JVM through bean factory methods such as Runtime.exec(). This issue affects Apache ActiveMQ Broker: before 5.19.7, from 6.0.0 before 6.2.6; Apache ActiveMQ All: before 5.19.7, from 6.0.0 before 6.2.6; Apache ActiveMQ: before 5.19.7, from 6.0.0 before 6.2.6.

Improper Input Validation, Improper Control of Generation of Code ('Code Injection') vulnerability in Apache ActiveMQ, Apache ActiveMQ Broker, Apache ActiveMQ All. An authenticated attacker can use the admin web console page to construct a malicious broker name that bypasses name validation to include an xbean binding that can be later used by a VM transport to load a remote Spring XML application. The attacker can then use the DestinationView mbean to send a message to trigger a VM transport creation that will reference this malicious broker name which can lead to loading the malicious Spring XML context file. Because Spring's ResourceXmlApplicationContext instantiates all singleton beans before the BrokerService validates the configuration, arbitrary code execution occurs on the broker's JVM through bean factory methods such as Runtime.exec(). This issue affects Apache ActiveMQ: before 5.19.6, from 6.0.0 before 6.2.5; Apache ActiveMQ Broker: before 5.19.6, from 6.0.0 before 6.2.5; Apache ActiveMQ All: before 5.19.6, from 6.0.0 before 6.2.5.

Denial of Service via Out of Memory vulnerability in Apache ActiveMQ Client, Apache ActiveMQ Broker, Apache ActiveMQ. ActiveMQ NIO SSL transports do not correctly handle TLSv1.3 handshake KeyUpdates triggered by clients. This makes it possible for a client to rapidly trigger updates which causes the broker to exhaust all its memory in the SSL engine leading to DoS. Note: TLS versions before TLSv1.3 (such as TLSv1.2) are broken but are not vulnerable to OOM. Previous TLS versions require a full handshake renegotiation which causes a connection to hang but not OOM. This is fixed as well. This issue affects Apache ActiveMQ Client: before 5.19.4, from 6.0.0 before 6.2.4; Apache ActiveMQ Broker: before 5.19.4, from 6.0.0 before 6.2.4; Apache ActiveMQ: before 5.19.4, from 6.0.0 before 6.2.4.

Incorrect Authorization (CWE-863) vulnerability in Apache Artemis, Apache ActiveMQ Artemis exists when an application using the OpenWire protocol attempts to create a non-durable JMS topic subscription on an address that doesn't exist with an authenticated user which has the "createDurableQueue" permission but does not have the "createAddress" permission and address auto-creation is disabled. In this circumstance, a temporary address will be created whereas the attempt to create the non-durable subscription should instead fail since the user is not authorized to create the corresponding address. When the OpenWire connection is closed the address is removed. This issue affects Apache Artemis: from 2.50.0 through 2.52.0; Apache ActiveMQ Artemis: from 2.0.0 through 2.44.0. Users are recommended to upgrade to version 2.53.0, which fixes the issue.

Missing Authentication for Critical Function (CWE-306) vulnerability in Apache Artemis, Apache ActiveMQ Artemis. An unauthenticated remote attacker can use the Core protocol to force a target broker to establish an outbound Core federation connection to an attacker-controlled rogue broker. This could potentially result in message injection into any queue and/or message exfiltration from any queue via the rogue broker. This impacts environments that allow both: - incoming Core protocol connections from untrusted sources to the broker - outgoing Core protocol connections from the broker to untrusted targets This issue affects: - Apache Artemis from 2.50.0 through 2.51.0 - Apache ActiveMQ Artemis from 2.11.0 through 2.44.0. Users are recommended to upgrade to Apache Artemis version 2.52.0, which fixes the issue. The issue can be mitigated by one of the following: - Remove Core protocol support from any acceptor receiving connections from untrusted sources. Incoming Core protocol connections are supported by default via the "artemis" acceptor listening on port 61616. See the "protocols" URL parameter configured for the acceptor. An acceptor URL without this parameter supports all protocols by default, including Core. - Use two-way SSL (i.e. certificate-based authentication) in order to force every client to present the proper SSL certificate when establishing a connection before any message protocol handshake is attempted. This will prevent unauthenticated exploitation of this vulnerability. - Implement and deploy a Core interceptor to deny all Core downstream federation connect packets. Such packets have a type of (int) -16 or (byte) 0xfffffff0. Documentation for interceptors is available at https://artemis.apache.org/components/artemis/documentation/latest/intercepting-operations.html .

See the following for more details: https://activemq.apache.org/security-advisories.data/CVE-2026-40046-announcement.txt https://www.cve.org/CVERecord?id=CVE-2026-40046 Original Report: Apache ActiveMQ does not properly validate the remaining length field which may lead to an overflow during the decoding of malformed packets. When this integer overflow occurs, ActiveMQ may incorrectly compute the total Remaining Length and subsequently misinterpret the payload as multiple MQTT control packets which makes the broker susceptible to unexpected behavior when interacting with non-compliant clients. This behavior violates the MQTT v3.1.1 specification, which restricts Remaining Length to a maximum of 4 bytes. The scenario occurs on established connections after the authentication process. Brokers that are not enabling mqtt transport connectors are not impacted. This issue affects Apache ActiveMQ: before 5.19.2, 6.0.0 to 6.1.8, and 6.2.0 Users are recommended to upgrade to version 5.19.2, 6.1.9, or 6.2.1, which fixes the issue.

Insertion of Sensitive Information into Log File vulnerability in Apache ActiveMQ Artemis. All the values of the broker properties are logged when the org.apache.activemq.artemis.core.config.impl.ConfigurationImpl logger has the debug level enabled. This issue affects Apache ActiveMQ Artemis: from 1.5.1 before 2.40.0. It can be mitigated by restricting log access to only trusted users. Users are recommended to upgrade to version 2.40.0, which fixes the issue.

No exploit published

No public exploit

A vulnerability exists in Apache ActiveMQ Artemis whereby a user with the createDurableQueue or createNonDurableQueue permission on an address can augment the routing-type supported by that address even if said user doesn't have the createAddress permission for that particular address. When combined with the send permission and automatic queue creation a user could successfully send a message with a routing-type not supported by the address when that message should actually be rejected on the basis that the user doesn't have permission to change the routing-type of the address. This issue affects Apache ActiveMQ Artemis from 2.0.0 through 2.39.0. Users are recommended to upgrade to version 2.40.0 which fixes the issue.

Apache ActiveMQ Artemis allows access to diagnostic information and controls through MBeans, which are also exposed through the authenticated Jolokia endpoint. Before version 2.29.0, this also included the Log4J2 MBean. This MBean is not meant for exposure to non-administrative users. This could eventually allow an authenticated attacker to write arbitrary files to the filesystem and indirectly achieve RCE. Users are recommended to upgrade to version 2.29.0 or later, which fixes the issue.

No exploit published

No public exploit

XStream is a Java library to serialize objects to XML and back again. In XStream before version 1.4.16, there is a vulnerability where the processed stream at unmarshalling time contains type information to recreate the formerly written objects. XStream creates therefore new instances based on these type information. An attacker can manipulate the processed input stream and replace or inject objects, that result in the deletion of a file on the local host. No user is affected, who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types. If you rely on XStream's default blacklist of the Security Framework, you will have to use at least version 1.4.16.

Apache ActiveMQ uses LocateRegistry.createRegistry() to create the JMX RMI registry and binds the server to the "jmxrmi" entry. It is possible to connect to the registry without authentication and call the rebind method to rebind jmxrmi to something else. If an attacker creates another server to proxy the original, and bound that, he effectively becomes a man in the middle and is able to intercept the credentials when an user connects. Upgrade to Apache ActiveMQ 5.15.12.
