VulnerabilityCVE-2026-57217cvecve-2026-57217cwe-863
Published: 07/10/2026 (07/10/2026, 20:25:29 UTC)
Source: CVE Database V5
Vendor/Project: rabbitmq
Product: rabbitmq-server

Description

RabbitMQ 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.
