CVE	Severity	Published▾	Status	Exploitation	Description
CVE-2026-33227	Medium	2026-04-07	Protected by Waratek	No public exploit	Improper validation and restriction of a classpath path name vulnerability in Apache ActiveMQ Client, Apache ActiveMQ Broker, Apache ActiveMQ All, Apache ActiveMQ Web, Apache ActiveMQ. In two instances (when creating a Stomp consumer and also browsing messages in the Web console) an authenticated user provided "key" value could be constructed to traverse the classpath due to path concatenation. As a result, the application is exposed to a classpath path resource loading vulnerability that could potentially be chained together with another attack to lead to exploit. This issue affects Apache ActiveMQ Client: before 5.19.3, from 6.0.0 before 6.2.2; Apache ActiveMQ Broker: before 5.19.3, from 6.0.0 before 6.2.2; Apache ActiveMQ All: before 5.19.3, from 6.0.0 before 6.2.2; Apache ActiveMQ Web: before 5.19.3, from 6.0.0 before 6.2.2; Apache ActiveMQ: before 5.19.3, from 6.0.0 before 6.2.2. Users are recommended to upgrade to version 5.19.4 or 6.2.3, which fixes the issue. Note: 5.19.3 and 6.2.2 also fix this issue, but that is limited to non-Windows environments due to a path separator resolution bug fixed in 5.19.4 and 6.2.3.
CVE-2022-35278	Medium	2022-08-23	Protected by Waratek	No public exploit	In Apache ActiveMQ Artemis prior to 2.24.0, an attacker could show malicious content and/or redirect users to a malicious URL in the web console by using HTML in the name of an address or queue.
CVE-2022-23913	High	2022-02-04	Protected by Waratek	No public exploit	In Apache ActiveMQ Artemis prior to 2.20.0 or 2.19.1, an attacker could partially disrupt availability (DoS) through uncontrolled resource consumption of memory.
CVE-2021-21350	Critical	2021-03-23	Protected by Waratek	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 execute arbitrary code 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-2021-21347	Critical	2021-03-23	Protected by Waratek	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 load and execute arbitrary code from a remote host 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-2021-21342	Critical	2021-03-23	Protected by Waratek	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 a server-side forgery request. 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-2020-11998	Critical	2020-09-10	Protected by Waratek	No public exploit	A regression has been introduced in the commit preventing JMX re-bind. By passing an empty environment map to RMIConnectorServer, instead of the map that contains the authentication credentials, it leaves ActiveMQ open to the following attack: https://docs.oracle.com/javase/8/docs/technotes/guides/management/agent.html "A remote client could create a javax.management.loading.MLet MBean and use it to create new MBeans from arbitrary URLs, at least if there is no security manager. In other words, a rogue remote client could make your Java application execute arbitrary code." Mitigation: Upgrade to Apache ActiveMQ 5.15.13
CVE-2014-3600	Critical	2017-10-27	Protected by Waratek	No public exploit	XML external entity (XXE) vulnerability in Apache ActiveMQ 5.x before 5.10.1 allows remote consumers to have unspecified impact via vectors involving an XPath based selector when dequeuing XML messages.
CVE-2014-3579	Critical	2017-10-27	Protected by Waratek	No public exploit	XML external entity (XXE) vulnerability in Apache ActiveMQ Apollo 1.x before 1.7.1 allows remote consumers to have unspecified impact via vectors involving an XPath based selector when dequeuing XML messages.
CVE-2016-4978	High	2016-09-27	Protected by Waratek	No public exploit	The getObject method of the javax.jms.ObjectMessage class in the (1) JMS Core client, (2) Artemis broker, and (3) Artemis REST component in Apache ActiveMQ Artemis before 1.4.0 might allow remote authenticated users with permission to send messages to the Artemis broker to deserialize arbitrary objects and execute arbitrary code by leveraging gadget classes being present on the Artemis classpath.
CVE-2014-3576	High	2015-08-14	Protected by Waratek	No public exploit	The processControlCommand function in broker/TransportConnection.java in Apache ActiveMQ before 5.11.0 allows remote attackers to cause a denial of service (shutdown) via a shutdown command.
