CVE-2026-92564Network attack vectorHinoki check available

Pre-authentication broker crash via unbounded type nesting

Published Sep 25, 2026 · Updated Sep 25, 2026

Uncontrolled recursion in Apache Qpid Broker-J 10.1.0 and earlier allows remote attackers to crash the broker before authentication. The AMQP 0-8, 0-9 and 0-9-1 field-table decoder recursively processes attacker-controlled nested values without a depth bound until the Java stack overflows. An unauthenticated network connection to an enabled legacy AMQP listener is sufficient to interrupt broker service.
