SCA: security update for symfony/html-sanitizer, symfony/symfony (GHSA-v3wm-qf9p-c549)

medium Tenable Self-Hosted Container Security Plugin ID 443185

Description

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

 - Symfony is a PHP framework for web and console applications and a set of reusable PHP components. From
 6.1.0 until 6.4.41, 7.4.13, and 8.0.13, UrlSanitizer::parse() rejected raw BiDi formatting characters but
 not percent-encoded forms and used an ASCII-only whitespace check, allowing sanitized URLs to retain
 visual-spoofing characters that downstream consumers could decode or display. This issue is fixed in
 versions 6.4.41, 7.4.13, and 8.0.13. (CVE-2026-48760)

Solution

Update the symfony/html-sanitizer library and its related packages to version 6.4.41 or later.
