RabbitMQ AWS: Active Debug Code
CVE-2026-9133 is a high-severity active debug code vulnerability in RabbitMQ AWS from AWS, with a CVSS 3.1 base score of 7.7 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. Affected RabbitMQ AWS versions: 0.1.0 through 0.2.0. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 1.11% chance of exploitation within 30 days, higher than 67% of scored CVEs.
High severity with no evidence of exploitation so far.

Official description
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.

The underlying weakness: Active Debug Code
The product is released with debugging code still enabled or active.
How developers prevent this class of flaw
- Remove debug code before deploying the application.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: no, technical impact: partial).
- Record last changed materially (score, affected products, status or references).
