JMS Client for RabbitMQ 1.x before 1.15.2 and 2.x before 2.2.0 is vulnerable to unsafe deserialization that can result in code execution via crafted StreamMessage data.

Apache Qpid AMQP 0-x JMS client before 6.0.4 and JMS (AMQP 1.0) before 0.10.0 does not restrict the use of classes available on the classpath, which might allow remote authenticated users with permission to send messages to deserialize arbitrary objects and execute arbitrary code by leveraging a crafted serialized object in a JMS ObjectMessage that is handled by the getObject function.

IBM MessageSight 1.x before 1.1.0.0-IBM-IMA-IT01015 does not verify that all of the characters of a password are correct, which makes it easier for remote authenticated users to bypass intended access restrictions by leveraging knowledge of a password substring.

The server in IBM MessageSight 1.x before 1.1.0.0-IBM-IMA-IT01015 allows remote attackers to cause a denial of service (daemon crash and message data loss) via malformed headers during a WebSockets connection upgrade.

IBM MessageSight 1.x before 1.1.0.0-IBM-IMA-IT01015 allows remote attackers to cause a denial of service (resource consumption) via WebSockets MQ Telemetry Transport (MQTT) data.

IBM MessageSight 1.x before 1.1.0.0-IBM-IMA-IT01015 allows remote attackers to cause a denial of service (daemon restart) via crafted MQ Telemetry Transport (MQTT) authentication data.
