Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process. RabbitMQ is a messaging and streaming broker. Prior to versions 3.13.15, 4.0.20, 4.1.11, 4.2.6, and 4.3.1, The shovel management resource's is_authorized/2 delegates to rabbit_mgmt_util:is_authorized_monitor/2, which accepts the monitoring tag. But allowed_methods includes DELETE, and delete_resource/2 deletes / restarts shovel runtime parameters with no additional role check. A monitoring user , intended to have read-only visibility , can therefore delete or restart any shovel in any vhost they can see. A read-only monitoring user can delete or restart any dynamic shovel , a state-changing operation that the equivalent /api/parameters endpoint correctly restricts to policymaker. Preconditions include rabbitmq_shovel + rabbitmq_shovel_management plugins enabled Attacker has credentials with the monitoring tag. This issue is fixed in versions 3.13.15, 4.0.20, 4.1.11, 4.2.6, and 4.3.1.
This issue is already fixed upstream in RabbitMQ 4.3.6, which is the version currently built for Fedora rawhide (rabbitmq-server-4.3.6-1.fc46) and Fedora 45 (rabbitmq-server-4.3.6-1.fc45). Fedora 44 (currently 4.2.9) and Fedora 43 (currently 4.0.9) still need attention; backports/rebases for the still-supported stable branches are being worked on. Leaving this report open to track that remaining work.
This issue is already addressed in the rabbitmq-server builds currently shipped in all maintained Fedora branches: * Fedora rawhide: rabbitmq-server-4.3.6-1.fc46 * Fedora 45: rabbitmq-server-4.3.6-1.fc45 * Fedora 44: rabbitmq-server-4.2.9-2.fc44 No new build is required for these branches, so closing as CURRENTRELEASE. Fedora 43 (rabbitmq-server-4.0.9) will NOT be updated for this CVE batch: the upstream 4.0.x line ended at 4.0.9 (later 4.0.x fixes are commercial-only, with no public OSS release) and Fedora 43 reaches end of life on 2026-12-09, so a backport to F43 is not worthwhile.
