VulnerabilityCVE-2026-57219cvecve-2026-57219cwe-200
Published: 07/10/2026 (07/10/2026, 20:22:26 UTC)
Source: CVE Database V5
Vendor/Project: rabbitmq
Product: rabbitmq-server

Description

RabbitMQ is a messaging and streaming broker. Prior to 3.13.15, 4.0.20, 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.
