CVE-2026-86722: Improper Authentication in WWBN AVideo
CVE-2026-86722 is an authentication bypass vulnerability in WWBN AVideo caused by improper caching of empty SQL result sets. This flaw allows attackers with a valid password to bypass email two-factor authentication on new devices because the confirmation code hash is generated from stale cached data. The vulnerability has a high severity score of 8.6 but no official patch or remediation guidance is currently available.
AI Analysis
Technical Summary
AVideo contains an authentication bypass vulnerability due to sqlDAL caching empty result sets that are not invalidated by writeSql. This leads to the confirmation code hash for email two-factor authentication failing to generate properly from stale cached empty results. Consequently, attackers who already possess a valid password can bypass the email two-factor authentication mechanism on new devices, undermining the intended multi-factor security control.
Potential Impact
Attackers with valid credentials can bypass the email two-factor authentication on new devices, potentially allowing unauthorized access despite the presence of multi-factor authentication. This reduces the effectiveness of the security control designed to protect user accounts and increases the risk of account compromise.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or workaround has been documented at this time.
