CVE-2026-17008
MediumCVSS 5.3Exploitation Probability (EPSS)
Low risk1th percentile - higher than 1% of all known CVEs
Summary
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.
Risk Assessment
The risk includes financial losses for the store, as orders can be fulfilled without full payment, leading to revenue loss.
Recommendation
It is recommended to immediately update the plugin to the latest version and implement verification of amount, receiver, and payment status in the IPN handler.
