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."}], "lastModified": "2026-10-20T13:32:39.940", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:broadcom:rabbitmq_server:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "603E40A7-6B53-47D4-A522-17B013CE7607", "versionEndExcluding": "3.13.15", "versionStartIncluding": "3.13.0"}, {"criteria": "cpe:2.3:a:broadcom:rabbitmq_server:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "9B5D0326-EB2B-40B8-98BD-ECE547F96DA4", "versionEndExcluding": "4.0.20", "versionStartIncluding": "4.0.0"}, {"criteria": "cpe:2.3:a:broadcom:rabbitmq_server:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "01F24286-9982-4592-A370-70E55D6572D5", "versionEndExcluding": "4.1.11", "versionStartIncluding": "4.1.0"}, {"criteria": "cpe:2.3:a:broadcom:rabbitmq_server:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "7179C053-B8C1-4B72-83EB-456125ED1AAF", "versionEndExcluding": "4.2.6", "versionStartIncluding": "4.2.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
