CVE-2026-68080Network attack vector

Authenticated service interruption via unbounded echo responses

Published Aug 5, 2026 · Updated Aug 5, 2026

Resource exhaustion in Apache Qpid Broker-J 10.0.1 and earlier allows remote authenticated users to interrupt service via AMQP echo flows. The AMQP 1.0 protocol plugin generates echo-flow responses without governing their rate, allowing a client to drive excessive broker resource use. Valid broker credentials and network access to an AMQP listener are required; published material does not specify whether exhaustion causes a hang or crash.
