CVE-2026-67413: RabbitMQ JMS topic exchange denial of service via regex wildcard expansion

CVE-2026-67413 · Severity: info · Published 2026-09-25

RabbitMQ is a message broker that routes messages between applications. The optional JMS topic exchange plugin allows authenticated users to bind queues using expressions called selectors. An authenticated user can craft a malicious selector with wildcard patterns that, when evaluated, causes the broker to consume excessive CPU and become unresponsive, disrupting message delivery for all users.

Technical details

The rabbitmq_jms_topic_exchange plugin's x-jms-topic exchange accepts client-controlled rjms_erlang_selector binding expressions in which LIKE wildcard evaluators (% and _) are expanded into overlapping PCRE fragments executed via raw re:run/3 without match or recursion limits. An authenticated tenant with bind and publish permissions can trigger pathological regex matching causing broker scheduler CPU exhaustion and denial of service.
