Detailsinfo

A vulnerability classified as problematic was found in WWBN AVideo up to 29.0. This vulnerability affects the function User::loginFromRequestIfNotLogged of the file objects/videoAddNew.json.php of the component CSRF Check Bypass. The manipulation of the argument user/pass with an unknown input leads to a cross-site request forgery vulnerability. The CWE definition for the vulnerability is CWE-352. The web application does not, or can not, sufficiently verify whether a well-formed, valid, consistent request was intentionally provided by the user who submitted the request. As an impact it is known to affect integrity. CVE summarizes:

AVideo (WWBN/AVideo) through 29.0 (commit e01e41ecc) is vulnerable to cross-site request forgery. objects/videoAddNew.json.php disables AVideo's automatic CSRF guard ($global['skipAutoCSRFCheck']) and the untrusted-request check ($global['bypassSameDomainCheck']) merely because 'user' and 'pass' parameters are present in the request; the values are never validated and are read from $_REQUEST, so an attacker can supply them in the query string of a cross-site request. Because User::loginFromRequestIfNotLogged() returns immediately when a session already exists, a victim who is authenticated by cookie satisfies the check while the attacker-supplied credentials are discarded. An attacker who lures an authenticated user with upload rights to visit a crafted page can therefore submit cross-origin requests that modify video records — including ownership transfer (setUsers_id), deletion of user-group access restrictions, can_download, can_share, only_for_paid, video_password, rating, status, creation date, and view count. For a victim with administrator or Permissions::canAdminVideos() rights, any video on the site can be altered, including removing group restrictions from private content. No patched version was available at the time of the advisory.

The advisory is shared for download at github.com. This vulnerability was named CVE-2026-92582 since 09/16/2026. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Successful exploitation requires user interaction by the victim. There are known technical details, but no exploit is available.
