The CVE-2025-22094 vulnerability exists within the `drupal-pattern-lab/unified-twig-extensions` package. The flaw is a Cross-site Scripting (XSS) issue caused by insufficient input filtering and output escaping in a Twig extension function. This function is designed to format text and is shared for use in both Drupal and Pattern Lab environments. When user-supplied data containing malicious JavaScript is passed through this specific function, the code is not properly neutralized before being rendered in the final HTML output. An attacker could exploit this by tricking a user into interacting with crafted malicious input, leading to the execution of arbitrary scripts in the victim’s browser context. It is critical to note that this vulnerability is only exploitable when the package is used outside of the Drupal framework, as Drupal’s core text sanitization routines would otherwise prevent the attack.
