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.
AnalysisAI
Sensitive credential disclosure in RabbitMQ affects installations running the management plugin with OAuth 2 configured via management.oauth_client_secret, prior to versions 3.13.15, 4.0.20, 4.1.11, and 4.2.6. The obsolete GET /api/auth endpoint returns the configured OAuth 2 client secret to unauthenticated callers, allowing any remote party with network reach to the management interface to harvest the credential and potentially impersonate the broker to its identity provider. …
