Publication date: 2026-09-25

Last updated on: 2026-09-25

Assigner: Apache Software Foundation

Description
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.
