What the vulnerability does

01Description

The MW WP Form plugin for WordPress is vulnerable to Information Exposure in all versions up to, and including, 5.1.2 via the _get_post_property_from_querystring() function due to insufficient restrictions on which posts can be included. This makes it possible for unauthenticated attackers to extract data from password protected, private, or draft posts that they should not have access to.

MW WP Form versions up to 5.1.2 contain an authorization flaw that allows unauthenticated attackers to read sensitive information.
