CVE-2026-92086
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 'postid' 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.
