 "title": "Contact Form 7 <= 6.2.4.1 - Authenticated (Editor+) Sensitive Information Exposure via 'user_' Form-Tag Default Options",
 "description": "The Contact Form 7 plugin for WordPress is vulnerable to Sensitive Information Exposure via the 'user_' default options of form-tags in all versions up to, and including, 6.2.4.1. This is due to the plugin mapping any 'user_*' option to an arbitrary property of the current user object instead of a restricted set of non-sensitive properties. This makes it possible for authenticated attackers with form editing access, editor-level and above, to make a form prefill fields with a logged-in visitor's password hash or activation key, which is then submitted back to them when the visitor sends the form.",
