SCA: security update for crass (GHSA-pq4g-8rxf-4g29)

medium Tenable Cloud Security Plugin ID 477764

Description

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

 - Crass is a Ruby CSS parser that is compliant with the CSS Syntax Level 3 specification. Prior to 1.0.8,
 Crass incorrectly treats a closing parenthesis after an escaped backslash as escaped while consuming the
 remnants of a bad URL. Crass therefore keeps declarations, style rules, or at-rules inside a bad URL token
 even though a browser treats them as live CSS. A sanitizer that parses untrusted CSS with Crass and
 reserializes it without rejecting the bad URL can allow CSS used for UI redress, external resource
 loading, or CSS-based data exfiltration, but this issue does not enable script execution in modern
 browsers. This issue is fixed in version 1.0.8. (CVE-2026-116695)

Solution

Update the crass library and its related packages to version 1.0.8 or later.
