CVE-2026-92086MW WP Form <= 5.1.7 - Unauthenticated Sensitive Information Exposure in 'post_id' Parameter
Medium 5.3
In plain English
A medium-severity information exposure in MW WP Form from websoudan. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 27% of all known vulnerabilities).
Official 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.
