CVE-2025-11570

Medium severity, CVSS 4.6. EPSS: 0.2% chance of exploitation in the next 30 days.

Versions of the package drupal-pattern-lab/unified-twig-extensions from 0.0.0 are vulnerable to Cross-site Scripting (XSS) due to insufficient filtering of data. **Note:** This is exploitable only if the code is executed outside of Drupal; the function is intended to be shared between Drupal and Pattern Lab. The package drupal-pattern-lab/unified-twig-extensions is unmaintained, the fix for this issue exists in version 1.1.1 of [drupal/unified_twig_ext](https://www.drupal.org/project/unified_twig_ext)
