Official description

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.
