{"id":"CVE-2026-57215","aliases":["GHSA-5cq3-v9jx-p3x3"],"url":"https://o3.security/vulnerability/CVE-2026-57215","summary":"RabbitMQ: Direct-reply-to binding persistence can lead to unauthorized reply-channel injection and persistent phantom","details":"RabbitMQ is a messaging and streaming broker. Prior to 3.13.15, 4.0.20, 4.1.11, and 4.2.6, RabbitMQ allows foreign bindings to amq.rabbitmq.reply-to destinations because volatile direct-reply-to queues can be accepted at bind and route time but are missing from Khepri-backed deletion checks, leaving persistent route entries after unbind. This issue is fixed in versions 3.13.15, 4.0.20, 4.1.11, and 4.2.6.","published":"2026-07-10T20:23:26.132Z","modified":"2026-09-27T18:26:46.118475580Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[],"fix":{"url":"https://github.com/rabbitmq/rabbitmq-server/commit/9055500d10ca7629dd2b051c6dc7a4b0bb8f6734","label":"rabbitmq/rabbitmq-server@9055500"},"references":[{"type":"WEB","url":"https://github.com/rabbitmq/rabbitmq-server/releases/tag/v4.2.6"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/57xxx/CVE-2026-57215.json"},{"type":"ADVISORY","url":"https://github.com/rabbitmq/rabbitmq-server/security/advisories/GHSA-5cq3-v9jx-p3x3"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-57215"},{"type":"FIX","url":"https://github.com/rabbitmq/rabbitmq-server/commit/9055500d10ca7629dd2b051c6dc7a4b0bb8f6734"},{"type":"FIX","url":"https://github.com/rabbitmq/rabbitmq-server/commit/c84f3c880e0f22b49c01237cf8f86e176eeadc72"},{"type":"FIX","url":"https://github.com/rabbitmq/rabbitmq-server/pull/15935"},{"type":"FIX","url":"https://github.com/rabbitmq/rabbitmq-server/pull/15938"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-27T18:26:46.118475580Z"}}
