CVE-2026-9273 Detail

Description

The Membership Plugin – Kadence Memberships plugin for WordPress (formerly Restrict Content) is vulnerable to password reset link poisoning leading to account takeover in all versions up to, and including, 4.0.0. This is due to the legacy lost-password handler rc_process_lost_password_form() consuming the attacker-controlled rc_redirect POST parameter into two unvalidated sinks in legacy/includes/forms.php: wp_redirect( esc_url( $_POST['rc_redirect'] ) . ... ) at line 243, and add_query_arg( array( 'key' => $key, 'login' => ... ), $_POST['rc_redirect'] ) inside rc_send_password_reset_email() at line 306. The nonce required to reach the handler is broadcast by the public [login_form] shortcode at line 207 to any anonymous visitor. This makes it possible for unauthenticated attackers to issue a password-reset request for any account (including administrators) whose reset email body points the victim at an attacker-controlled host carrying a valid reset key/login. When the victim clicks the link, the reset key leaks to the attacker, who can replay it against the legitimate site to complete account takeover.
