High technical severity with public exploit material referenced by a structured source; prioritise exposed affected systems while verifying vendor guidance.
Canonical’s release and source-package findings are shown separately from local repository availability.
A published vendor fix does not prove that a matching update is enabled and installable on a particular asset. Confirm the local package candidate before scheduling remediation.

Patch availableRabbitMQ is a messaging and streaming broker. Prior to 3.13.15, 4.0.21, 4.1.11, and 4.2.6, RabbitMQ topic authorization can allow restricted topic writes and binds during metadata-store failures because topic-permission lookup errors from Khepri can collapse to undefined, which the internal backend treats as allow. This issue is fixed in versions 3.13.15, 4.0.21, 4.1.11, and 4.2.6.

The application performs an authorisation check, but it does not correctly enforce the required permission boundary.
An attacker operating through a network path may attempt exploitation with low privileges. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
A structured CVE source labels at least one public reference as exploit material. BlackTree has not independently validated that it is safe, reliable or weaponised.
CWE-863: Incorrect Authorization. The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check.
