What is CVE-2026-9133?

The Amazon MQ RabbitMQ AWS plugin prior to version 0.2.1 contains a vulnerability due to the presence of active debug code in its ARN resolver. This debug code permits remote authenticated users to exploit the PUT /api/aws/arn/validate endpoint, potentially allowing them to read arbitrary files that the RabbitMQ process can access. To address this vulnerability, users are highly encouraged to upgrade to version 0.2.1 and, if RabbitMQ is configured for TLS, rotate any private certificate keys associated with the connections for enhanced security.

Affected Version(s)

RabbitMQ AWS 0.1.0 <= 0.2.0
