CVE-2026-34394 Details
Description
WWBN AVideo is an open source video platform. In versions 26.0 and prior, AVideo's admin plugin configuration endpoint (admin/save.json.php) lacks any CSRF token validation. There is no call to isGlobalTokenValid() or verifyToken() before processing the request. Combined with the application's explicit SameSite=None cookie policy, an attacker can forge cross-origin POST requests from a malicious page to overwrite arbitrary plugin settings on a victim administrator's session. Because the plugins table is included in the ignoreTableSecurityCheck() array in objects/Object.php, standard table-level access controls are also bypassed. This allows a complete takeover of platform functionality by reconfiguring payment processors, authentication providers, cloud storage credentials, and more. At time of publication, there are no publicly available patches.
A cross-site request forgery (CSRF) vulnerability has been identified in WWBN AVideo versions through 26.0. The issue arises in the admin plugin configuration endpoint, which lacks CSRF token validation. This vulnerability allows an attacker to forge cross-origin POST requests that overwrite arbitrary plugin settings on a victim administrator's session. The absence of standard table-level access controls for the plugins table further exacerbates the issue, enabling a complete takeover of platform functionality by reconfiguring payment processors, authentication providers, cloud storage credentials, and more.
It is recommended to add CSRF token validation to the admin/save.json.php endpoint, immediately after the admin check. This can be done by calling isGlobalTokenValid() and verifying the token before processing the request.
