## Description

The Contact Form 7 plugin for WordPress is vulnerable to Sensitive Information Exposure via user-related special mail-tags in all versions up to, and including, 6.1.7. This is due to the plugin accepting any mail-tag name beginning with '_user_' and mapping it to an arbitrary WP_User property or user meta key. This makes it possible for authenticated attackers with Editor-level access or above, or any role allowed to edit contact forms, to place tags such as [_user_user_pass] or arbitrary user meta keys in a form's mail template. When a logged-in user such as an administrator submits that form, the attacker receives that user's password hash or other private user meta by email.
