CVE-2026-34394
In versions 26.0 and prior, AVideo's admin plugin configuration endpoint (admin/save.json.php) lacks any CSRF token validation.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.23%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
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.
