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.","evidence":"cve:CVE-2026-67230","products":[{"name":{"value":"rabbitmq-server","evidence":"/containers/cna/affected/0/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]}],"severity":"medium","structured":{"id":"CVE-2026-67230","aliases":["CVE-2026-67230"],"metrics":[{"cvssV4_0":{"version":"4.0","baseScore":6.3,"attackVector":"NETWORK","baseSeverity":"MEDIUM","vectorString":"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","userInteraction":"NONE","attackComplexity":"LOW","attackRequirements":"PRESENT","privilegesRequired":"NONE","subIntegrityImpact":"NONE","vulnIntegrityImpact":"NONE","subAvailabilityImpact":"NONE","vulnAvailabilityImpact":"LOW","subConfidentialityImpact":"NONE","vulnConfidentialityImpact":"NONE"}}],"affected":[{"vendor":"rabbitmq","product":"rabbitmq-server","versions":[{"status":"affected","version":">= 4.2.0, < 4.2.6"},{"status":"affected","version":">= 4.1.0, < 4.1.11"},{"status":"affected","version":">= 4.0.0, < 4.0.20"},{"status":"affected","version":">= 3.13.0, < 3.13.15"}]}],"modified":"2026-09-29T19:22:26.179Z","provider":"cve","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"],"provider_metadata":{"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-67230","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"total"}],"version":"2.0.3","timestamp":"2026-09-29T19:22:14.972578Z"}}}],"providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-29T19:22:26.179Z"}}],"cna":{"orgId":"a0819718-46f1-4df5-94e2-005712e83aaa","shortName":"GitHub_M","dateUpdated":"2026-09-25T16:01:40.340Z"}}},"related_cves":[{"value":"CVE-2026-67230","evidence":"/cveMetadata/cveId"}],"security_relevant":true,"severity_evidence":"/containers/cna/metrics"}}],"next_after":3963,"next_before":3963}
