{"schema":"threatline.record/2","record":{"id":"CVE-2026-67237","aliases":["GHSA-2rf7-f6r6-8rwh"],"summary":"RabbitMQ: Reflected XSS via the OAuth bootstrap JS endpoint","details":"RabbitMQ is a messaging and streaming broker. From 4.2.0 until 4.2.8 and 4.3.2, set_token_auth/2 inserted a bearer token from the Authorization header or access_token cookie into OAuth bootstrap JavaScript without escaping, allowing attacker-controlled token content to execute JavaScript in the management UI origin. The endpoint is exposed before authentication only when management.oauth_enabled is true, and exploitation through the cookie path additionally requires the attacker to plant an access_token cookie on the management host. This issue is fixed in versions 4.2.8 and 4.3.2.","categories":["Unclassified"],"product":"rabbitmq-server","vendor":"rabbitmq","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-67237","source_modified_at":"2026-09-25T17:53:59.829Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"rabbitmq-server","vendor":"rabbitmq","versions":[{"status":"affected","version":">= 4.2.0, < 4.2.8"},{"status":"affected","version":">= 4.3.0, < 4.3.2"}],"defaultStatus":null},{"source":"GitHub Advisory Database","source_url":"https://github.com/rabbitmq/rabbitmq-server/security/advisories/GHSA-2rf7-f6r6-8rwh","source_modified_at":"2026-07-29T15:06:26Z","fetched_at":"2026-10-23T20:39:26.410340Z","package":{"ecosystem":"other","name":"rabbitmq-server"},"range":">= 4.2.0, < 4.2.8"},{"source":"GitHub Advisory Database","source_url":"https://github.com/rabbitmq/rabbitmq-server/security/advisories/GHSA-2rf7-f6r6-8rwh","source_modified_at":"2026-07-29T15:06:26Z","fetched_at":"2026-10-23T20:39:26.410340Z","package":{"ecosystem":"other","name":"rabbitmq-server"},"range":">= 4.3.0, < 4.3.2"}],"fixed_versions":[{"source":"GitHub Advisory Database","source_url":"https://github.com/rabbitmq/rabbitmq-server/security/advisories/GHSA-2rf7-f6r6-8rwh","source_modified_at":"2026-07-29T15:06:26Z","fetched_at":"2026-10-23T20:39:26.410340Z","package":{"ecosystem":"other","name":"rabbitmq-server"},"version":"4.2.8"},{"source":"GitHub Advisory Database","source_url":"https://github.com/rabbitmq/rabbitmq-server/security/advisories/GHSA-2rf7-f6r6-8rwh","source_modified_at":"2026-07-29T15:06:26Z","fetched_at":"2026-10-23T20:39:26.410340Z","package":{"ecosystem":"other","name":"rabbitmq-server"},"version":"4.3.2"}],"cvss":7.5,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00452,"percentile":0.3827,"score_date":"2026-10-23"},"published_at":"2026-09-25T16:05:16.417Z","modified_at":"2026-09-25T17:53:59.829Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-67237","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-25T17:53:59.829Z"},{"source":"GitHub Advisory Database","url":"https://github.com/rabbitmq/rabbitmq-server/security/advisories/GHSA-2rf7-f6r6-8rwh","fetched_at":"2026-10-23T20:39:26.410340Z","source_modified_at":"2026-07-29T15:06:26Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-67237","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","GitHub Advisory Database","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/rabbitmq/rabbitmq-server/security/advisories/GHSA-2rf7-f6r6-8rwh","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/rabbitmq/rabbitmq-server/commit/5cd6d841d84450324a4613501ed917d98828af23","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/rabbitmq/rabbitmq-server/commit/a8041d528c1a71af4cb75ade247ed082fe6b83fb","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/rabbitmq/rabbitmq-server/releases/tag/v4.2.8","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/rabbitmq/rabbitmq-server/releases/tag/v4.3.2","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":"no","technical_impact":"total","assessed_at":"2026-09-25T17:53:50.928309Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-25T17:53:59.829Z","content_hash":"3b6e07ad7f411f921f13427426669ef38734d2743a70d81edbb55746c162906d"}}
