{"id":"UBUNTU-CVE-2026-57212","details":"RabbitMQ is a messaging and streaming broker. Prior to 3.13.14, 4.0.19, 4.1.10, and 4.2.5, the rabbitmq_management HTTP API accepts oversized valid JSON bodies on with_decode and direct_request paths because read_complete_body checks the accumulated size before the final chunk but not the final combined size. This issue is fixed in versions 3.13.14, 4.0.19, 4.1.10, and 4.2.5.","modified":"2026-07-15T19:47:47.849466679Z","published":"2026-07-10T21:16:00Z","upstream":["CVE-2026-57212"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-57212"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-57212"},{"type":"REPORT","url":"https://github.com/rabbitmq/rabbitmq-server/commit/3976d148901bdfa82e1cd60b7a4534e073266ba5"},{"type":"REPORT","url":"https://github.com/rabbitmq/rabbitmq-server/commit/b8fc2ef7c50a2797d15e1ea7cf34f290032303bb"},{"type":"REPORT","url":"https://github.com/rabbitmq/rabbitmq-server/pull/15712"},{"type":"REPORT","url":"https://github.com/rabbitmq/rabbitmq-server/pull/15714"},{"type":"REPORT","url":"https://github.com/rabbitmq/rabbitmq-server/releases/tag/v4.2.5"},{"type":"REPORT","url":"https://github.com/rabbitmq/rabbitmq-server/security/advisories/GHSA-5cmq-vp28-xqrj"}],"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_name":"rabbitmq-server","binary_version":"3.5.7-1ubuntu0.16.04.4+esm2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-57212.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-2026-57212.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-2026-57212.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_name":"rabbitmq-server","binary_version":"3.9.27-0ubuntu0.2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-57212.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_version":"3.12.1-1ubuntu1.4","binary_name":"rabbitmq-server"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-57212.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-2026-57212.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:N/VI:N/VA:H/SC:N/SI:N/SA:L"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
