SCA: security update for loofah (GHSA-9wjq-cp2p-hrgf)

medium Tenable Cloud Security Plugin ID 445053

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Loofah is a general library for manipulating and transforming HTML/XML documents and fragments, built on
 top of Nokogiri. Prior to 2.25.2, Loofah's HTML5 sanitizer applies its local-reference restriction only to
 the xlink:href attribute on SVG use and feImage elements, while browsers also accept the plain href
 attribute. A crafted sanitized SVG can therefore reference an arbitrary same-origin external document; use
 may render external SVG content containing scripts or other dangerous content, and feImage may load
 external images for tracking. Applications that sanitize user-supplied SVG with Loofah's default allowlist
 are affected. This issue is fixed in version 2.25.2. (CVE-2026-73490)

Solution

Update the loofah library and its related packages to version 2.25.2 or later.
