Critical vendor advisory CVE-2026-33297

Summary

WWBN AVideo is an open source video platform. Prior to version 26.0, the `setPassword.json.php` endpoint in the CustomizeUser plugin allows administrators to set a channel password for any user. Due to a logic error in how the submitted password value is processed, any password containing non-numeric characters is silently coerced to the integer zero before being stored. This means that regardless of the intended password, the stored channel password becomes 0, which any visitor can trivially guess to bypass channel-level access control. Version 26.0 contains a patch for the issue.
