CVE-2025-6220: Themefic Ultimate Addons For Contact Form 7 remote code execution (CVSS 7.2)

Description

The Ultra Addons for Contact Form 7 plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the 'save_options' function in all versions up to, and including, 3.5.12.
