CVE-2025-31476

Ein Angreifer kann mehrere Schwachstellen in Drupal ausnutzen, um Sicherheitsmaßnahmen zu umgehen und Cross-Site-Scripting-Schwachstellen auszuführen.

A vulnerability was identified in `tarteaucitron.js`, allowing a user with high privileges (access to the site's source code or a CMS plugin) to enter a URL containing an insecure scheme such as `javascript:alert()`. Before the fix, URL validation was insufficient, which could allow arbitrary JavaScript execution if a user clicked on a malicious link. ## Impact An attacker with high privileges could insert a link exploiting an insecure URL scheme, leading to: - Execution of arbitrary JavaScript code - Theft of sensitive data through phishing attacks - Modification of the user interface behavior ## Fix https://github.com/AmauriC/tarteaucitron.js/commit/2fa1e01023bce2e4b813200600bb1619d56ceb02 The issue was resolved by enforcing strict URL validation, ensuring that they start with `http://` or `https://` before being used.

This module enables sites to comply with the European cookie law using tarteaucitron.js. The module doesn't sufficiently filter user-supplied markup inside of content leading to a persistent Cross Site Scripting (XSS) vulnerability. This vulnerability is mitigated by the fact that an attacker needs to be able to insert specific data attributes in the page.
