WWBN AVideo Authorization Bypass via Users_affiliations add.json.php
WWBN AVideo through commit 9c39d8c8b4c1f75540788d6b391740852ceb0732 contains an authorization bypass vulnerability in the Users_affiliations add.json.php endpoint that allows authenticated users to forge two-party consent records by supplying the counterparty's agreement timestamp. Attackers can create a forged affiliation with status='a' and then reassign video ownership to arbitrary users through the videoAddNew.json.php endpoint, which trusts the forged affiliation as an authorization term.
