Unauthenticated server-side requests to arbitrary domains
Published Apr 8, 2026 · Updated Apr 8, 2026
Server-side request forgery in Global Payments GlobalPayments WooCommerce 1.18.3 and earlier allows remote attackers to send server-side requests. The public advisory does not identify the request handler, attacker-controlled parameter, or failed destination check; it states only that the site requests an arbitrary attacker-selected domain. Exploitation is unauthenticated but requires high attack complexity and can expose information from other services reachable by the WordPress server.
