Linux Distros Unpatched Vulnerability : CVE-2026-41239
medium Nessus Plugin ID 310045
Language:
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.- DOMPurify is a DOM-only cross-site scripting sanitizer for HTML, MathML, and SVG. Starting in version 1.0.10 and prior to version 3.4.0, `SAFE_FOR_TEMPLATES` strips `{{...}}` expressions from untrusted HTML.
This works in string mode but not with `RETURN_DOM` or `RETURN_DOM_FRAGMENT`, allowing XSS via template- evaluating frameworks like Vue 2. Version 3.4.0 patches the issue. (CVE-2026-41239)
Note that Nessus relies on the presence of the package as reported by the vendor.
