CVE-2026-67413

CVE-2026-67413 · RabbitMQ: Authenticated RabbitMQ JMS Topic Selector Users Can Consume Broker CPU with an Unbounded LIKE Regular Expression

This page contains facts from public vulnerability sources. Check the original advisory before updating.

RabbitMQ is a messaging and streaming broker. From 4.0.0 until 4.0.23, 4.1.14, 4.2.9, and 4.3.3, the optional rabbitmq_jms_topic_exchange plugin's x-jms-topic exchange accepted a client-controlled rjms_erlang_selector binding expression whose LIKE evaluator expanded percent and underscore wildcards into overlapping PCRE fragments. It executed those fragments with raw re:run/3 without match or recursion limits, allowing an authenticated tenant that can bind and publish to consume broker scheduler CPU and deny service with pathological selectors. This issue is fixed in versions 4.0.23, 4.1.14, 4.2.9, and 4.3.3.
