CVE-2026-49977

Ein entfernter Angreifer kann mehrere Schwachstellen in verschiedenen Drupal Erweiterungen ausnutzen, um Daten zu manipulieren oder offenzulegen, sowie um Cross-Site Scripting Angriffe durchzuführen.

### Summary tarteaucitron provides a list of cookies and buttons to delete them. If an attacker can write HTML with data attributes, they could create an element that silently deletes a cookie when clicked and trick a user to delete this cookie. ### Details `tarteaucitron.cookie.purge()` is called on any element with the `purgeBtn` class. It does not check if the element is a legitimate tarteaucitron button or if the cookie corresponds to a service handled by tarteaucitron. ### PoC ```html <a class="purgeBtn" data-cookie="foo">Click me!</a> ``` If someone has a cookie with this name and clicks on the link, the cookie is silently deleted. ### Impact The impact is limited because this only works on cookies without HttpOnly=true and the attacker has to know the name of the cookie.
