CVE-2022-25275 Drupal core Information Disclosure vulnerability

What is CVE-2022-25275?

CVE-2022-25275 is a high-severity missing authorization vulnerability in Drupal Drupal, published on 26 Apr 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

In some situations, the Image module does not correctly check access to image files not stored in the standard public files directory when generating derivative images using the image styles system. Access to a non-public file is checked only if it is stored in the "private" file system. However, some contributed modules provide additional file systems, or schemes, which may lead to this vulnerability. This vulnerability is mitigated by the fact that it only applies when the site sets (Drupal 9) $config['image.settings']['allow_insecure_derivatives'] or (Drupal 7) $conf['image_allow_insecure_derivatives'] to TRUE. The recommended and default setting is FALSE, and Drupal core does not provide a way to change that in the admin UI. Some sites may require configuration changes following this security release. Review the release notes for your Drupal version if you have issues accessing files or image styles after updating.
