Settings modification via missing CSRF nonce verification
Published May 20, 2026 · Updated May 20, 2026
Cross-site request forgery in Child Height Predictor by Ostheimer 1.3 and earlier allows remote attackers to alter plugin settings. The options() handler accepts a forged settings POST without wp_nonce_field(), check_admin_referer(), or wp_verify_nonce(), then persists values with update_option(). Exploitation requires an administrator to visit an attacker-controlled page, and the demonstrated consequence is unauthorized modification of settings such as unit preferences.
