CVE-2026-9133

What it is

Active debug code exists in the ARN resolver of amazon-mq rabbitmq-aws before version 0.2.1. A debug ARN scheme (arn:aws-debug:file) accepted by the PUT /api/aws/arn/validate validation endpoint might allow remote authenticated users to perform arbitrary file reads on any file accessible to the RabbitMQ process. To remediate this issue, customers should upgrade to version 0.2.1 of rabbitmq-aws. If RabbitMQ is configured to use TLS for connections, we also recommend rotating any associated private certificate keys.
