CVE-2026-119749

GetPaid WordPress Plugin < 2.8.63 Negative Quantity Payment Bypass

Published Nov 4, 2026 CVSS 4.0 · 8.7 High EPSS < 1% KEV · Not listed
Description
The GetPaid plugin for WordPress before 2.8.63 contains an improper input validation vulnerability that allows unauthenticated attackers to bypass payment processing by submitting a negative item quantity on a public payment form. Attackers can exploit the unchecked quantity value in process_item() to produce a negative line subtotal that reduces the invoice total to zero, causing process_free_payment() to mark the invoice as paid without any actual gateway charge.
