The endpoint validates only the Category::canCreateCategory() capability and a CSRF nonce before passing the attacker-supplied $_REQUEST['id'] to Category::deleteAssets(), which recursively removes {systemRootPath}videos/categories/assets/{id}/. It omits the Category::userCanEditCategory() ownership check enforced by the sibling Category::delete(). On installations where the non-default usersCanCreateNewCategories setting is enabled, an authenticated non-admin user with the canUpload capability can send a POST request with an arbitrary category ID and recursively delete any category's on-disk asset directory (icons/images). Category records and videos are not deleted. As of the advisory publication no patched version was available.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":42,"depthScoreParts":{"impact":29.7,"likelihood":0,"exploitation":12,"ransomware":0},"changes":[{"seq":204291,"id":"CVE-2026-89257","ts":1789490449283,"field":"exploit_available","old":"false","new":"true"}]}
