Published Sep 9, 2022 · Updated Apr 28, 2026

Server-Side Request Forgery in Rank Math SEO 1.0.95 and earlier allows remote attackers to make the WordPress server request attacker-chosen URLs. The plugin insufficiently validates user-supplied URL input before issuing outbound requests, allowing access to arbitrary domains and potentially internal services.
