Linux Distros Unpatched Vulnerability : CVE-2026-49342

medium Nessus Plugin ID 321842

Synopsis

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

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- YARD is a documentation generation tool for the Ruby programming language. Prior to version 0.9.44, YARD's static cache lookup reads a request path before the router's path cleanup runs. When a server is configured with a document root, a traversal path such as `/../yard-cache-secret.html` is joined against that root and can return a readable sibling `.html` file outside the intended static tree. Version 0.9.44 patches the issue. (CVE-2026-49342)

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

Solution

There is no known solution at this time.
