CVE-2026-59320Network attack vectorHinoki check available

Listener denial of service via exhausted link credit

Published Aug 27, 2026 · Updated Aug 27, 2026

Denial of service in Spring AMQP 4.1.0 allows remote authenticated users to stall AMQP 1.0 listeners with failing deliveries. On the listener-exception path, a configured container ErrorHandler fails to replenish the receiver credit consumed by each delivery whose processing throws. An affected application must use the container-level ErrorHandler; after the initial credits are consumed, the broker stops delivery while isRunning() remains true.
