CVE-2026-92550Network attack vectorHinoki check available

Pre-authentication service interruption via excessive decoder allocation

Published Sep 25, 2026 · Updated Sep 25, 2026

Excessive allocation in Apache Qpid Broker-J 10.1.0 and earlier allows remote attackers to interrupt the broker before authentication. The AMQP 0-8/0-9/0-9-1 decoder treats attacker-controlled type size or count values as allocation sizes without enforcing a safe bound. An unauthenticated network connection can exhaust broker memory and disrupt message service; no data disclosure or modification is reported.
