CVE-2026-92573: Improper Handling of Highly Compressed Data (Data Amplification)

Improper handling of compressed data in the shared GZIP decompressor used for AMQP 0-8/0-9/0-9-1 and AMQP 0-10 message delivery, message conversion and HTTP management JSON rendering allows authenticated message producers to exhaust memory and disrupt broker availability via processing without a...

CVE-2026-92608: Uncaught Exception

Improper handling of property-encoding exceptions in AMQP 1.0-to-AMQP 0-10 message conversion allows authenticated message producers to disrupt delivery to AMQP 0-10 consumers via message properties that the target encoder does not handle correctly. This issue affects Apache Qpid Broker-J: throug...

CVE-2026-92609: Session Fixation

Session fixation in HTTP management authentication allows remote attackers to gain unauthorized access to an authenticated management session via reuse of a session identifier retained across successful authentication. This issue affects Apache Qpid Broker-J: through 10.1.0. Users are recommended...
