Unauthenticated open redirect via unvalidated destination parameter
Published Nov 24, 2025 · Updated Nov 24, 2025
Open redirect in WP Front User Submit before 5.0.0 allows remote attackers to send users to an untrusted site through a crafted URL. The fus_form_register shortcode flow accepts the redirect query parameter as the post-registration destination without validating its origin. The target must visit the crafted registration page and submit the form; the resulting navigation exposes the target to attacker-controlled content.
