Under certain circumstances, the Drupal core form API evaluates form element access incorrectly. This may lead to a user being able to alter data they should not have access to.
No forms provided by Drupal core are known to be vulnerable. However, forms added through contributed or custom modules or themes may be affected.
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.
Solution:
Install the latest version:
If you are using Drupal 9.4, update to Drupal 9.4.3.
If you are using Drupal 9.3, update to Drupal 9.3.19.
Multiple vulnerabilities have been discovered in Google Chrome, the most severe of which could allow for arbitrary code execution. Google Chrome is a web browser used to access the Internet. Successful exploitation of the most severe of these vulnerabilities could allow for arbitrary code execution in the context of the logged on user. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.
