## Description

The Gutenverse Form – Contact Form Builder, Block Form & Booking Form plugin for WordPress is vulnerable to CSV Injection via form entry submissions in all versions up to, and including, 3.2.1, due to insufficient neutralization of formula elements when submitted entry values are written to the form action and entries CSV exports. This makes it possible for unauthenticated attackers to submit form values beginning with spreadsheet formula characters that are embedded in exported CSV files and may run when a site administrator exports the entries and opens the file in a vulnerable spreadsheet application.
