Vulnerability Title
AVideo through 29.0 Cross-User Category Asset Deletion via Missing Ownership Check
Source: CVE Program / CVE List V5
Vulnerability Description
AVideo through 29.0 contains an insecure direct object reference (IDOR) vulnerability in objects/categoryDeleteAssets.json.php. 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.
