Name of the Vulnerable Software and Affected Versions Drupal Theme Negotiation by Rules versions prior to 1.2.1

Description A Cross-Site Request Forgery (CSRF) issue exists in the Theme Negotiation by Rules module. The module allows site builders to create “theme rule” config entities to render pages with different themes based on specific conditions. The module utilizes a simple GET request to disable or enable theme rules, enabling attackers to manipulate these rules by deceiving site administrators into clicking malicious links. Successful exploitation requires the attacker to know the machine name of the theme rule.

Recommendations Update to version 1.2.1 or later.
