Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

 - RabbitMQ is a messaging and streaming broker. Prior to 3.13.14, 4.0.19, 4.1.10, and 4.2.5, the rabbitmq_federation_management plugin renders the consumer_tag field on the Federation Status page without HTML escaping, allowing a user who can configure a federation upstream or policy to execute JavaScript in the browser of a user viewing that page. This issue is fixed in versions 3.13.14, 4.0.19, 4.1.10, and 4.2.5. (CVE-2026-57213)

Note that Nessus relies on the presence of the package as reported by the vendor.
