Short explanation
Quick PayPal Payments plugin before 5.7.50 suffers from unauthenticated payment bypass via PayPal IPN due to missing validation checks. CVSS score is 5.3 (medium). Patch status is UNKNOWN. No fixed version is confirmed in public sources.
This allows attackers to manipulate order status without valid payment, leading to unauthorized order processing and financial loss. The lack of validation in IPN handler makes it exploitable without authentication.
What should be done?
- Upgrade to version 5.7.51 or later if available, as the vulnerability is fixed in newer versions.
- Verify vendor advisories for official patch details.
- Do not use versions prior to 5.7.50 without patching.
The sources give limited detail on some technical conditions. Review the chain of evidence below before deciding how to act.
Chain of evidence and sources
Quick PayPal Payments WordPress plugin'ı 5.7.50 sürümüne kadar, ödeme miktarı, alıcı ve ödeme durumu doğrulaması eksikliği nedeniyle PayPal IPN aracılığıyla kimlik doğrulamasız ödeme geçişi yapabilir. Sadece sipariş token eşleşmesiyle siparişin ödendiği olarak işaretlenmesi sağlanır.
Açık, CVSS 3.1 puanı 5.3 ile orta şiddetli olup, bütünlükte sınırlı etki yaratır ancak kimlik doğrulamasız sipariş işleme riski vardır.
Resmî yama durumu mevcut değildir; yama değerlendirmesi 'BİLİNMEYEN' olarak belirtilmiş ve üretici kaynaklarından güvenilir bilgi yoktur.
Show the technical text from the sources
The Quick Paypal Payments WordPress plugin through 5.7.50 does not verify the paid amount, receiver, or payment status in its PayPal IPN handler and marks an order paid on an order-token match alone, so a buyer who pays an arbitrary small amount can have a full-price order marked paid.
