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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-79"],"vendors":[],"products":[],"references":[{"url":"https://github.com/rabbitmq/rabbitmq-server/commit/5cd6d841d84450324a4613501ed917d98828af23","tags":[]},{"url":"https://github.com/rabbitmq/rabbitmq-server/commit/a8041d528c1a71af4cb75ade247ed082fe6b83fb","tags":[]},{"url":"https://github.com/rabbitmq/rabbitmq-server/releases/tag/v4.2.8","tags":[]},{"url":"https://github.com/rabbitmq/rabbitmq-server/releases/tag/v4.3.2","tags":[]},{"url":"https://github.com/rabbitmq/rabbitmq-server/security/advisories/GHSA-2rf7-f6r6-8rwh","tags":[]}],"exploitRefs":[{"url":"https://github.com/rabbitmq/rabbitmq-server/commit/5cd6d841d84450324a4613501ed917d98828af23","tags":[]},{"url":"https://github.com/rabbitmq/rabbitmq-server/commit/a8041d528c1a71af4cb75ade247ed082fe6b83fb","tags":[]},{"url":"https://github.com/rabbitmq/rabbitmq-server/releases/tag/v4.2.8","tags":[]},{"url":"https://github.com/rabbitmq/rabbitmq-server/releases/tag/v4.3.2","tags":[]},{"url":"https://github.com/rabbitmq/rabbitmq-server/security/advisories/GHSA-2rf7-f6r6-8rwh","tags":[]}],"hasPoc":true,"ai":null}
