Summary
WWBN AVideo 6.5 through 29.7.1 contains an authentication bypass vulnerability that allows unauthenticated attackers to log in as any user via Hybridauth social login display names. Attackers can set their X, Facebook, Yahoo or LinkedIn display name to a victim's username and withhold email, causing login.json.php or oauth2.php to log them in as that account, including administrators, without a password.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
The maintainers of WWBN/AVideo published their own advisory on GitHub. Reviewed sources take precedence over it.
