Description

CVE-2026-9133 is a high-severity vulnerability in the amazon-mq rabbitmq-aws plugin before version 0.2.1. It involves active debug code in the ARN resolver that accepts a debug ARN scheme allowing remote authenticated users to read arbitrary files accessible to the RabbitMQ process. The vulnerability affects versions 0.1.0 through 0.2.0 inclusive. AWS has released version 0.2.1 to remediate this issue and recommends upgrading to this version. Additionally, if TLS is used, rotating private certificate keys is advised.
