From 4.0.0 until 4.3.3, 4.2.9, 4.1.14, and 4.0.23, AMQP 1.0 management GET /bindings exposes full binding topology to any authenticated AMQP user without resource/management permission checks. the AMQP 1.0 HTTP-over-AMQP management endpoint GET /bindings (the rabbitamqpmanagement handler) enumerates bindings between an arbitrary source exchange and destination queue/exchange in the caller's virtual host without performing any resource-level permission check. Unlike every sibling operation in the same module (which call checkresourceaccess / bindingchecks), the GET handler ignores the authenticated User and returns the binding list unchanged. As a result, any authenticated AMQP 1.0 client that can open a management link pair , including users with no management/monitoring/policymaker/administrator tag , can enumerate the complete binding topology (source exchanges, destination queues/exchanges, routing keys, and binding arguments) of the virtual host they can access. The equivalent HTTP management API (GET /api/bindings) Confidentiality impact: a non-management AMQP 1.0 user can enumerate the complete routing topology of any virtual host it can connect to , every (source exchange, destination queue/exchange, routing key, binding arguments) This issue is fixed in versions 4.3.3, 4.2.9, 4.1.14, and 4.0.23."}], "lastModified": "2026-10-15T20:22:41.003", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:broadcom:rabbitmq_server:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "D5D13FFE-E0D9-4199-B413-C75E4A525550", "versionEndExcluding": "4.0.23", "versionStartIncluding": "4.0.0"}, {"criteria": "cpe:2.3:a:broadcom:rabbitmq_server:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "D1298756-9945-4567-A288-410FAF5B54AE", "versionEndExcluding": "4.1.14", "versionStartIncluding": "4.1.0"}, {"criteria": "cpe:2.3:a:broadcom:rabbitmq_server:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "D35C2182-6B6E-4E76-98E7-6C928D64CCA8", "versionEndExcluding": "4.2.9", "versionStartIncluding": "4.2.0"}, {"criteria": "cpe:2.3:a:broadcom:rabbitmq_server:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "E6CDECF0-FDCF-4C38-AD9D-F7B1F1246AEB", "versionEndExcluding": "4.3.3", "versionStartIncluding": "4.3.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
