CVE-2026-89251Network attack vectorHinoki check available

Wallet credit manipulation via unverified ad impressions

Published Sep 11, 2026 · Updated Sep 11, 2026

Missing authorization in WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 allows remote authenticated users to mint wallet credits. The plugin/AD_Server/log.php handler accepts attacker-chosen labels and treats label=start as a verified ad impression before crediting the campaign video's owner. Any logged-in account can repeatedly submit the request for any campaign video, corrupting YPTWallet balances without an ad playback event.
