Prior to 3.13.15, 4.0.20, 4.1.11, and 4.2.6, RabbitMQ does not perform authorization checks on passive queue.declare and exchange.declare AMQP 0-9-1 operations, allowing any authenticated user who can connect to a virtual host to enumerate queue and exchange names and read queue message and consumer counts. This issue is fixed in versions 3.13.15, 4.0.20, 4.1.11, and 4.2.6.","modified":"2026-07-15T19:48:35.982983083Z","published":"2026-07-10T21:16:00Z","upstream":["CVE-2026-57221"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-57221"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-57221"},{"type":"REPORT","url":"https://github.com/rabbitmq/rabbitmq-server/commit/709a14e49e06c138a8cd672c9809ca34a2767962"},{"type":"REPORT","url":"https://github.com/rabbitmq/rabbitmq-server/commit/dc3d1aa4f5c3331a425ee599b45be9423a2e83fc"},{"type":"REPORT","url":"https://github.com/rabbitmq/rabbitmq-server/pull/16085"},{"type":"REPORT","url":"https://github.com/rabbitmq/rabbitmq-server/pull/16090"},{"type":"REPORT","url":"https://github.com/rabbitmq/rabbitmq-server/releases/tag/v4.2.6"},{"type":"REPORT","url":"https://github.com/rabbitmq/rabbitmq-server/security/advisories/GHSA-9q2j-2hq8-22r2"}],"affected":[{"package":{"name":"rabbitmq-server","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/rabbitmq-server?arch=source&distro=esm-infra%2Fxenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.5.4-1","3.5.4-3","3.5.4-3.1","3.5.7-1","3.5.7-1ubuntu0.16.04.1","3.5.7-1ubuntu0.16.04.2","3.5.7-1ubuntu0.16.04.4","3.5.7-1ubuntu0.16.04.4+esm1","3.5.7-1ubuntu0.16.04.4+esm2"],"ecosystem_specific":{"binaries":[{"binary_version":"3.5.7-1ubuntu0.16.04.4+esm2","binary_name":"rabbitmq-server"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-57221.json"}},{"package":{"name":"rabbitmq-server","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/rabbitmq-server?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.6.10-1","3.6.10-1ubuntu0.1","3.6.10-1ubuntu0.3","3.6.10-1ubuntu0.4","3.6.10-1ubuntu0.5"],"ecosystem_specific":{"binaries":[{"binary_name":"rabbitmq-server","binary_version":"3.6.10-1ubuntu0.5"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-57221.json"}},{"package":{"name":"rabbitmq-server","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/rabbitmq-server?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.7.8-4ubuntu2","3.7.18-1","3.8.2-0ubuntu1","3.8.2-0ubuntu1.1","3.8.2-0ubuntu1.2","3.8.2-0ubuntu1.3","3.8.2-0ubuntu1.4","3.8.2-0ubuntu1.5","3.8.3-0ubuntu0.1","3.8.3-0ubuntu0.2","3.8.3-0ubuntu0.3"],"ecosystem_specific":{"binaries":[{"binary_name":"rabbitmq-server","binary_version":"3.8.3-0ubuntu0.3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-57221.json"}},{"package":{"name":"rabbitmq-server","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/rabbitmq-server?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.8.9-3ubuntu1","3.9.8-1","3.9.8-2","3.9.8-3","3.9.8-5","3.9.8-6","3.9.13-1","3.9.13-1ubuntu0.22.04.1","3.9.13-1ubuntu0.22.04.2","3.9.27-0ubuntu0.1","3.9.27-0ubuntu0.2"],"ecosystem_specific":{"binaries":[{"binary_version":"3.9.27-0ubuntu0.2","binary_name":"rabbitmq-server"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-57221.json"}},{"package":{"name":"rabbitmq-server","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/rabbitmq-server?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.12.1-1","3.12.1-1ubuntu1","3.12.1-1ubuntu1.2","3.12.1-1ubuntu1.4"],"ecosystem_specific":{"binaries":[{"binary_name":"rabbitmq-server","binary_version":"3.12.1-1ubuntu1.4"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-57221.json"}},{"package":{"name":"rabbitmq-server","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/rabbitmq-server?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.0.5-8ubuntu2","4.0.5-10ubuntu1","4.0.5-10ubuntu2","4.0.5-10ubuntu3","4.0.5-10ubuntu4","4.0.5-10ubuntu5"],"ecosystem_specific":{"binaries":[{"binary_name":"rabbitmq-server","binary_version":"4.0.5-10ubuntu5"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-57221.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:L/SI:N/SA:N"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N"},{"type":"Ubuntu","score":"medium"}]}
