Vulnerability Title
MW WP Form <= 5.1.7 - Unauthenticated Sensitive Information Exposure in 'post_id' Parameter
Source: CVE Program / CVE List V5
Vulnerability Description
The MW WP Form plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 5.1.7 via the 'post_id' parameter. This makes it possible for unauthenticated attackers to extract personally identifiable information from other users' form inquiry records, including submitted names, email addresses, and free-text message bodies, by enumerating sequential post IDs. Exploitation requires the targeted form to have the querystring setting enabled, but this is a standard documented feature of the plugin.
