Published Aug 16, 2023 · Updated May 5, 2025

Reflected XSS in Fullworks Plugins WP Easy Pay 4.0.4 and earlier allows remote attackers to run scripts via crafted URLs. The plugin outputs URLs built with add_query_arg without context-appropriate escaping, allowing attacker-controlled query data to enter page markup. Exploitation requires an administrator or another high-privilege user to follow the crafted link; scripts then run in that user's browser session.
