CVE-2025-13083

Ein Angreifer kann mehrere Schwachstellen in Drupal Core ausnutzen, um einen Denial of Service Angriff durchzuführen, um beliebigen Programmcode auszuführen, um falsche Informationen darzustellen, und um Informationen offenzulegen.

Use of Web Browser Cache Containing Sensitive Information vulnerability in Drupal Drupal core allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Drupal core: from 8.0.0 before 10.4.9, from 10.5.0 before 10.5.6, from 11.0.0 before 11.1.9, from 11.2.0 before 11.2.8, from 7.0 before 7.103.

Use of Web Browser Cache Containing Sensitive Information vulnerability in Drupal Drupal core allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Drupal core: from 8.0.0 before 10.4.9, from 10.5.0 before 10.5.6, from 11.0.0 before 11.1.9, from 11.2.0 before 11.2.8, from 7.0 before 7.103.

The core `system` module handles downloads of private and temporary files. Contrib modules can define additional kinds of files (schemes) that may also be handled by the `system` module. In some cases, files may be served with the HTTP header `Cache-Control: public` when they should be uncacheable. This can lead to some users getting cached versions of files with information they should not be able to access. For example, files may be cached by Varnish or a CDN. This vulnerability is mitigated by the following: 1. Drupal must be configured to handle non-public files using a custom or contributed module providing an additional file scheme. 2. An attacker must know to request a file that has previously been requested by a more-privileged user, and that file must still be cached.
