{"id":"CVE-2026-67230","published":"2026-09-25T17:17:11.600","lastModified":"2026-09-29T20:17:22.350","description":"RabbitMQ is a messaging and streaming broker. From 3.13.0 until 3.13.15, 4.0.20, 4.1.11, and 4.2.6, the Web STOMP WebSocket handler enforced neither max_frame_size nor login_timeout before authentication, allowing an unauthenticated client to keep a connection alive with a slow stream of small frames and accumulate unbounded pre-authentication state. The rabbitmq_web_stomp plugin must be enabled, and no authentication is required to reach the vulnerable path. This issue is fixed in versions 3.13.15, 4.0.20, 4.1.11, and 4.2.6.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-770"],"vendors":[],"products":[],"references":[{"url":"https://github.com/rabbitmq/rabbitmq-server/commit/0b4080fa5d6f797b6331d0ce1db2b4bacd34560e","tags":[]},{"url":"https://github.com/rabbitmq/rabbitmq-server/commit/8138edae6d2beaafe699a41a754d17420bdc2068","tags":[]},{"url":"https://github.com/rabbitmq/rabbitmq-server/commit/c1000ba89052608c01c052d98016403ba6e92222","tags":[]},{"url":"https://github.com/rabbitmq/rabbitmq-server/releases/tag/v4.2.6","tags":[]},{"url":"https://github.com/rabbitmq/rabbitmq-server/security/advisories/GHSA-7v63-j4gm-p4rh","tags":[]}],"exploitRefs":[{"url":"https://github.com/rabbitmq/rabbitmq-server/commit/0b4080fa5d6f797b6331d0ce1db2b4bacd34560e","tags":[]},{"url":"https://github.com/rabbitmq/rabbitmq-server/commit/8138edae6d2beaafe699a41a754d17420bdc2068","tags":[]},{"url":"https://github.com/rabbitmq/rabbitmq-server/commit/c1000ba89052608c01c052d98016403ba6e92222","tags":[]},{"url":"https://github.com/rabbitmq/rabbitmq-server/releases/tag/v4.2.6","tags":[]},{"url":"https://github.com/rabbitmq/rabbitmq-server/security/advisories/GHSA-7v63-j4gm-p4rh","tags":[]}],"hasPoc":true,"ai":null}
