Summary
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. Unauthenticated attackers can extract personally identifiable information from other users' form inquiry records, including names, email addresses and message bodies, by enumerating sequential post IDs. Exploitation requires the targeted form to have the querystring setting enabled, which is a standard documented feature of the plugin.
