RabbitMQ Vulnerability Threatens Enterprise Systems
A vulnerability in RabbitMQ's management web interface allows unauthenticated attackers to obtain the broker's confidential OAuth client secret. This secret leak enables attackers to impersonate the broker to the identity provider and obtain administrator tokens, potentially gaining control over users, messages, queues, and broker settings. The flaw affects configurations where the OAuth client secret is set and the management port is accessible to untrusted networks. RabbitMQ instances without the management plugin or without a configured client secret are not affected. The vulnerability was introduced in RabbitMQ version 3.13.0 and has been fixed in versions 3.13.15, 4.0.20, 4.1.11, 4.2.6, and 4.3.0. No evidence of exploitation in the wild has been reported.
AI Analysis
Technical Summary
CVE-2026-5721 is a vulnerability in RabbitMQ's management web interface that exposes the OAuth client secret via an unauthenticated open management endpoint. This allows attackers who can reach the management port to retrieve the secret and impersonate the broker to the OAuth 2/OIDC identity provider, obtaining administrator tokens. The vulnerability was introduced in RabbitMQ 3.13.0 and affects deployments where the OAuth client secret is configured and the management interface is accessible from untrusted networks, such as cloud or multi-tenant environments. The issue has been addressed in RabbitMQ versions 3.13.15, 4.0.20, 4.1.11, 4.2.6, and 4.3.0. Additionally, related medium-severity flaws affecting queue and exchange enumeration were fixed in these versions. The risk is highest when the management port is exposed to untrusted networks. No known exploitation has been observed in the wild.
Potential Impact
Successful exploitation allows unauthenticated attackers to obtain the RabbitMQ broker's OAuth client secret, enabling them to impersonate the broker to the identity provider and obtain administrator tokens. This grants control over users, messages, queues, and broker settings, posing a significant risk to enterprise systems, especially in cloud or multi-tenant environments where the management interface is exposed. Deployments without a configured OAuth client secret or without the management plugin are not affected. No known exploitation in the wild has been reported.
Mitigation Recommendations
A fix is available in RabbitMQ versions 3.13.15, 4.0.20, 4.1.11, 4.2.6, and 4.3.0. Organizations should update their RabbitMQ deployments to one of these fixed versions immediately. If patching is not possible, block access to the management port from untrusted networks and ensure the management interface is not exposed to the internet. Additionally, rotate the OAuth client secret after applying patches or access restrictions. Implement network segmentation to limit access to the management interface. These steps will mitigate the risk posed by this vulnerability.
