Until a fix is available, users should consider disabling or restricting the vulnerable PayPal IPN plugin or implementing additional verification to ensure IPNs are bound to the legitimate merchant account.
Description
CVE-2026-126543 is a high-severity vulnerability in WWBN AVideo up to version 29.7.1. It involves improper verification of payment authenticity in the PayPal IPN handling script (plugin/PayPalYPT/ipnV2.php). Attackers can exploit this flaw by forwarding legitimate verified recurring payment notifications from their own PayPal accounts with arbitrary user IDs, resulting in unauthorized crediting of wallet balances on the affected site.
