Group type deletion via missing CSRF validation
Published Sep 15, 2026 · Updated Sep 15, 2026
Cross-site request forgery in Concrete CMS 9.0.0 through 9.5.2 allows remote attackers to delete a custom group type. The dashboard group type controller's delete action processes a state-changing request without validating its CSRF token. Exploitation requires an authenticated user with group type management permission to visit attacker-controlled content, and the resulting deletion alters site configuration.
