The WP Frontend Profile plugin for WordPress versions up to and including 1.2.1 is vulnerable to Cross-Site Request Forgery. This is because the ‘wp-frontend-profile/functions/save-fields.php’ file has missing or incorrect validation for nonce in the wpfep_save_password() function. This means that unauthenticated attackers can change the passwords of other users if they can get a site administrator to click on a link or do something similar.
