CVE-2026-17008: Unknown Quick PayPal Payments

Medium severity, CVSS 5.3. EPSS: 0.2% chance of exploitation in the next 30 days.

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.
