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.","evidence":"cve:CVE-2026-61837","products":[{"name":{"value":"rabbitmq-server","evidence":"/containers/cna/affected/0/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]}],"severity":"medium","structured":{"id":"CVE-2026-61837","aliases":["CVE-2026-61837"],"metrics":[{"cvssV4_0":{"version":"4.0","baseScore":6.3,"attackVector":"NETWORK","baseSeverity":"MEDIUM","vectorString":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:N/SC:H/SI:N/SA:N","userInteraction":"NONE","attackComplexity":"LOW","attackRequirements":"NONE","privilegesRequired":"LOW","subIntegrityImpact":"NONE","vulnIntegrityImpact":"NONE","subAvailabilityImpact":"NONE","vulnAvailabilityImpact":"NONE","subConfidentialityImpact":"HIGH","vulnConfidentialityImpact":"NONE"}}],"affected":[{"vendor":"rabbitmq","product":"rabbitmq-server","versions":[{"status":"affected","version":">= 4.3.0, < 4.3.3"},{"status":"affected","version":">= 4.2.0, < 4.2.9"},{"status":"affected","version":">= 4.1.0, < 4.1.14"},{"status":"affected","version":">= 4.0.0, < 4.0.23"}]}],"modified":"2026-09-29T19:27:59.221Z","provider":"cve","references":["https://github.com/rabbitmq/rabbitmq-server/security/advisories/GHSA-w9hf-476r-443x","https://github.com/rabbitmq/rabbitmq-server/commit/341e3f2795ebd1f816e712530f651a3221d23ad9","https://github.com/rabbitmq/rabbitmq-server/commit/b94004dea530f961b3dc649d94969b89f1a3183f","https://github.com/rabbitmq/rabbitmq-server/releases/tag/v4.2.9","https://github.com/rabbitmq/rabbitmq-server/releases/tag/v4.3.3"],"provider_metadata":{"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-61837","role":"CISA Coordinator","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-09-29T19:27:34.351868Z"}}}],"references":[{"url":"https://github.com/rabbitmq/rabbitmq-server/security/advisories/GHSA-w9hf-476r-443x","tags":["exploit"]}],"providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-29T19:27:59.221Z"}}],"cna":{"orgId":"a0819718-46f1-4df5-94e2-005712e83aaa","shortName":"GitHub_M","dateUpdated":"2026-09-25T16:22:43.927Z"}}},"related_cves":[{"value":"CVE-2026-61837","evidence":"/cveMetadata/cveId"}],"security_relevant":true,"severity_evidence":"/containers/cna/metrics"}}],"next_after":3960,"next_before":3960}
