CVE-2026-89251: Insufficient Verification of Data Authenticity in WWBN AVideo
AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 fails to validate ad impressions in plugin/AD_Server/log.php, allowing logged-in users to submit arbitrary label values that trigger unverified wallet credits to campaign video owners. Attackers can repeatedly POST label=start requests to mint YPTWallet balance for any campaign video without proof an ad actually played.
AI Analysis
Technical Summary
The vulnerability exists in the plugin/AD_Server/log.php file of AVideo, where insufficient verification of ad impression data allows authenticated users to manipulate wallet credits. Specifically, the application does not validate that an ad impression actually occurred before crediting the wallet, enabling attackers to submit arbitrary 'label=start' POST requests to fraudulently increase YPTWallet balances for any campaign video.
Potential Impact
Successful exploitation allows attackers with login access to fraudulently increase wallet balances associated with campaign videos, potentially leading to financial loss or abuse of the platform's credit system. The vulnerability requires authenticated user privileges but no user interaction or elevated privileges beyond login. There is no indication of remote code execution or data disclosure beyond wallet credit manipulation.
Mitigation Recommendations
No patch or official fix information is provided in the available data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to trusted users and monitor for suspicious wallet credit activity related to ad impressions.
