Detailsinfo

A vulnerability has been found in WWBN AVideo up to 29.0 and classified as problematic. Affected by this vulnerability is the function Category::deleteAssets of the file objects/categoryDeleteAssets.json.php of the component Category Asset Deletion. The manipulation of the argument id with an unknown input leads to a resource injection vulnerability. The CWE definition for the vulnerability is CWE-99. The product receives input from an upstream component, but it does not restrict or incorrectly restricts the input before it is used as an identifier for a resource that may be outside the intended sphere of control. As an impact it is known to affect integrity, and availability. The summary by CVE is:

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.

The advisory is shared at github.com. This vulnerability is known as CVE-2026-89257 since 09/11/2026. The exploitation appears to be easy. The attack can be launched remotely. Technical details are known, but no exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 09/11/2026).
