Doc Text:	A flaw was found in Apache Qpid Broker-J. An authenticated attacker can cause a Denial of Service (DoS) by sending specially crafted compressed data to the message broker. Because the shared decompression mechanism does not enforce limits on decompressed output size during Advanced Message Queuing Protocol (AMQP) message processing and management rendering, processing this input can exhaust system memory and disrupt service availability.

Description OSIDB Bzimport 2026-09-25 08:21:37 UTC

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 decompressed-output limit.

This issue affects Apache Qpid Broker-J: through 10.1.0.

Users are recommended to upgrade to version 10.1.1, which fixes the issue.
