## Description

The Gutenverse Form – Contact Form Builder, Block Form & Booking Form plugin for WordPress is vulnerable to Sensitive Information Exposure via the form input dynamic default value feature in all versions up to, and including, 3.2.1, due to the 'loopDataMetaKey' and 'userDataMetaKey' block attributes allowing any post or user meta key to be read and rendered into the input value without an allowlist. This makes it possible for authenticated attackers, with Contributor-level access and above, to expose arbitrary, including private, post meta of posts rendered in the block's context, such as posts listed by a Query Loop, on the front end.
