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.","state":0,"publishedAt":"2026-09-25T16:01:40.34+00:00","modifiedAt":"2026-09-29T19:22:26.179+00:00","affected":[{"ecosystem":"Vendor product","name":"rabbitmq-server","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"rabbitmq\",\n                    \"product\": \"rabbitmq-server\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 4.2.0, < 4.2.6\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 4.1.0, < 4.1.11\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 4.0.0, < 4.0.20\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 3.13.0, < 3.13.15\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","score":6.3,"severity":"MEDIUM"}],"references":["https://github.com/rabbitmq/rabbitmq-server/security/advisories/GHSA-7v63-j4gm-p4rh","https://github.com/rabbitmq/rabbitmq-server/commit/0b4080fa5d6f797b6331d0ce1db2b4bacd34560e","https://github.com/rabbitmq/rabbitmq-server/commit/8138edae6d2beaafe699a41a754d17420bdc2068","https://github.com/rabbitmq/rabbitmq-server/commit/c1000ba89052608c01c052d98016403ba6e92222","https://github.com/rabbitmq/rabbitmq-server/releases/tag/v4.2.6"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-67230","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-67230","identifiers":["CVE-2026-67230"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
