{"id":"AZL-105750","summary":"CVE-2026-67222 affecting package rabbitmq-server 3.13.7-9","details":"RabbitMQ is a messaging and streaming broker. From 3.13.0 until 3.13.15, 4.0.20, 4.1.11, and 4.2.6, mechanisms/1 applied list_to_atom/1 to every colon-delimited token in an attacker-controlled auth_mechanism value, permanently consuming Erlang VM atoms and allowing the node to be crashed with a large request. Exploitation requires the Shovel or Federation plugin to be in use, and setting auth_mechanism requires the policymaker tag. This issue is fixed in versions 3.13.15, 4.0.20, 4.1.11, and 4.2.6.","modified":"2026-10-07T05:34:51Z","published":"2026-09-25T17:17:10Z","upstream":["CVE-2026-67222"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-67222"}],"affected":[{"package":{"name":"rabbitmq-server","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/rabbitmq-server"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"3.13.7-9"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-105750.json"}}],"schema_version":"1.9.0"}
