CVE-2022-25275

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.
