{"schema":"threatline.record/2","record":{"id":"CVE-2026-67230","aliases":["GHSA-7v63-j4gm-p4rh"],"summary":"RabbitMQ: Web-STOMP unbounded pre-auth accumulation","details":"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.","categories":["Unclassified"],"product":"rabbitmq-server","vendor":"rabbitmq","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-67230","source_modified_at":"2026-09-29T19:22:26.179Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"rabbitmq-server","vendor":"rabbitmq","versions":[{"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","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":6.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00583,"percentile":0.47171,"score_date":"2026-10-23"},"published_at":"2026-09-25T16:01:40.340Z","modified_at":"2026-09-29T19:22:26.179Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-67230","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-29T19:22:26.179Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-67230","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/rabbitmq/rabbitmq-server/security/advisories/GHSA-7v63-j4gm-p4rh","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/rabbitmq/rabbitmq-server/commit/0b4080fa5d6f797b6331d0ce1db2b4bacd34560e","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/rabbitmq/rabbitmq-server/commit/8138edae6d2beaafe699a41a754d17420bdc2068","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/rabbitmq/rabbitmq-server/commit/c1000ba89052608c01c052d98016403ba6e92222","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/rabbitmq/rabbitmq-server/releases/tag/v4.2.6","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"total","assessed_at":"2026-09-29T19:22:14.972578Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-29T19:22:26.179Z","content_hash":"580619019effd4384c39fd404126f1d20240f9c7e4379378c40c4ab84436839d"}}
