The WP Forms Connector plugin for WordPress is vulnerable to Information Exposure in all versions up to, and including, 1.8. The plugin registers the REST route wp/v3/user/list/ (callback userDetail()) with permission callback set to ' return true', and the function's home-grown authentication only verifies that the supplied 'Username' HTTP header maps to an administrator account and that a 'Password' HTTP header is non-empty. It never validates the password with wp check password() (unlike the sibling delete wc user() function which does). This makes it possible for unauthenticated attackers to retrieve sensitive information for any registered user ID — including the WordPress password hash (user pass) and email address — by sending a request with a valid administrator login name (commonly the default 'admin') and any arbitrary password value.
