HighCVSS 7.5Exploitation Probability (EPSS)
Low risk27th percentile — higher than 27% of all known CVEs
Summary
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/<id> with permission_callback set to '__return_true', allowing access to sensitive information without proper authorization.
Risk Assessment
Unauthenticated attackers can access sensitive data, such as the WordPress password hash and email address of any registered user, posing a serious security threat to the organization.
Recommendation
It is recommended to update the plugin to the latest version and to review and improve the authorization mechanisms to secure access to sensitive information.
Original NVD description (English source)
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/<id> (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.
