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.
