Summary
AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains an authentication bypass vulnerability where sqlDAL caches empty result sets that writeSql never invalidates. Attackers with a valid password can bypass email two-factor authentication on new devices because the confirmation code hash fails to generate from the stale cached empty result.

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.
