NVD Description

Note: Versions mentioned in the description apply only to the upstream rabbitmq-server4.2 package and not the rabbitmq-server4.2 package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

RabbitMQ is a messaging and streaming broker. Prior to 3.13.15, 4.0.20, 4.1.11, and 4.2.6, the obsolete GET /api/auth endpoint can disclose the OAuth 2 client secret on RabbitMQ installations configured with management.oauth_client_secret, exposing credentials to unauthenticated callers when the management plugin and that OAuth configuration are enabled. This issue is fixed in versions 3.13.15, 4.0.20, 4.1.11, and 4.2.6.
