Vulnerability Description
The Child Height Predictor by Ostheimer plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to and including 1.3. This is due to missing nonce verification in the options() function, which handles plugin settings updates. The form template does not include a wp_nonce_field() call, and the handler never calls check_admin_referer() or wp_verify_nonce(). This makes it possible for unauthenticated attackers to trick a site administrator into clicking a link or visiting a malicious page that submits a forged POST request, causing unauthorized changes to the plugin settings such as unit preferences to be persisted to the database via update_option().
