WP-Forms-Connector, CVE-2026-9178

CVE, Research URL: CVE-2026-9178
Home page URL: Security reports for WP-Forms-Connector
Application: WP-Forms-Connector
Published on: Jun 24, 2026
Research Description: 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.
Affected versions: max 1.8.
Status: vulnerable
