CVE-2025-6220 is an arbitrary file upload vulnerability in the Ultra Addons for Contact Form 7 WordPress plugin affecting all versions up to and including 3.5.12. The issue is caused by missing file type validation in the plugin's 'save_options' function. Because uploaded files are not properly restricted to safe types, an authenticated attacker with Administrator-level privileges or higher can upload arbitrary files to the server hosting the affected WordPress site. If the uploaded file is executable in the target environment, this can lead to remote code execution.

This repository contains a working exploit for CVE-2025-6220, targeting the Ultimate Addons for Contact Form 7 WordPress plugin (versions <= 3.5.12). The exploit is implemented in Python (CVE-2025-6220.py) and automates the process of authenticating as an administrator, extracting a required nonce from the plugin's settings page, and uploading a PHP web shell via a vulnerable file upload mechanism in the plugin's 'save_options' functionality. The uploaded shell is placed in a web-accessible directory (/wp-content/uploads/itinerary-fonts/shell.php), allowing the attacker to execute arbitrary system commands via HTTP requests. The README.md provides detailed background, manual exploitation steps, and code snippets from the vulnerable plugin. The exploit requires valid administrator credentials and is not a detection script but a fully operational exploit with a hardcoded web shell payload.
