vulnrichment / CVE-2026-39366
| Advisory ID | vulnrichment/CVE-2026-39366 |
| Aliases | |
| Summary | WWBN AVideo is an open source video platform. In versions 26.0 and prior, the PayPal IPN v1 handler at plugin/PayPalYPT/ipn.php lacks transaction deduplication, allowing an attacker to replay a single legitimate IPN notification to repeatedly inflate their wallet balance and renew subscriptions. The newer ipnV2.php and webhook.php handlers correctly deduplicate via PayPalYPT_log entries, but the v1 handler was never updated and remains actively referenced as the notify_url for billing plans. |
