CVE-2026-9178
Received Received - Intake
Information Exposure in WP Forms Connector Plugin

Publication date: 2026-06-24

Last updated on: 2026-06-24

Assigner: Wordfence

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.

Executive Summary

The WP Forms Connector plugin for WordPress has a vulnerability in all versions up to and including 1.8 that allows information exposure. The plugin registers a REST route that uses a custom authentication method which only checks if the 'Username' HTTP header corresponds to an administrator account and that the 'Password' HTTP header is non-empty. However, it does not actually verify the password using the proper WordPress password check function. This flaw allows unauthenticated attackers to send requests with any password and a valid administrator username to retrieve sensitive information about any registered user ID.

Specifically, attackers can obtain sensitive data such as the WordPress password hash (user_pass) and email address of users.

Impact Analysis

This vulnerability can have a significant impact by exposing sensitive user information without proper authentication. Attackers can retrieve password hashes and email addresses of any registered user, which could lead to further attacks such as password cracking, unauthorized access, phishing, or identity theft.

Because the vulnerability allows unauthenticated access to administrator-level information, it poses a high confidentiality risk.
