RabbitMQ is a messaging and streaming broker. In versions 3.13.7 and prior, RabbitMQ is logging authorization headers in plaintext encoded in base64. When querying RabbitMQ api with HTTP/s with basic authentication it creates logs with all headers in request, including authorization headers which show base64 encoded username:password. This is easy to decode and afterwards could be used to obtain control to the system depending on credentials. This issue has been patched in version 4.0.8.

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.
