CVE-2026-58002Public exploitNetwork attack vector

Ownership reassignment via forged affiliation consent

Published Aug 22, 2026 · Updated Aug 22, 2026

Authorization bypass in AVideo through commit 9c39d8c8b4c1f75540788d6b391740852ceb0732 allows remote authenticated users to reassign video ownership. Users_affiliations/add.json.php accepts the counterparty's agreement timestamp, and save() treats both nonempty dates as mutual consent. A regular account with upload permission can forge an active affiliation and make videoAddNew.json.php store new content under an arbitrary user's identity.
