Sources and claim methodology

Upstream source description

AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a stored cross-site scripting vulnerability in the YPTWallet plugin where user-supplied CryptoWallet values are base64-encoded but not HTML-escaped before storage in wallet_log.information. Administrators viewing pending withdrawal requests in pendingRequests.php execute the stored markup in their session, allowing attackers to perform administrative actions via same-origin fetch requests.
