Technical Analysis
CVE-2026-86722 is an authentication bypass vulnerability in WWBN AVideo identified in commit c3edcc274c389816d434acadac07ee78eaf330c1. The issue arises because sqlDAL caches empty result sets that the writeSql function does not invalidate. As a result, when a user with a valid password attempts to authenticate on a new device, the email two-factor authentication confirmation code hash is generated from stale cached empty data, allowing bypass of the second factor.
Potential Impact
Attackers who have obtained a valid password can bypass the email two-factor authentication mechanism on new devices, reducing the effectiveness of multi-factor authentication and increasing the risk of unauthorized access.
