The Metform Elementor Contact Form Builder plugin for WordPress is vulnerable to CSV injection in versions up to, and including, 3.3.0. This allows unauthenticated attackers to embed untrusted input into exported CSV files, which can result in code execution when these files are downloaded and opened on a local system with a vulnerable configuration.
Weakness
The product saves user-provided information into a Comma-Separated Value (CSV) file, but it does not neutralize or incorrectly neutralizes special elements that could be interpreted as a command when the file is opened by a spreadsheet product.
Affected Software
