CVE-2026-90987 PUBLISHED

Easy PayPal & Stripe Buy Now Button 1.8 - 2.0.5 - Unauthenticated Payment Amount Manipulation via Client-Supplied Price

Assigner: WPScan
Reserved: 14.09.2026 Published: 02.10.2026 Updated: 02.10.2026

The Easy PayPal & Stripe Buy Now Button WordPress plugin before 2.0.6 does not derive the payment amount on the server, taking it from a client-supplied field, so an unauthenticated attacker sets an arbitrary lower price for a purchase.
