CVE-2026-82901

Ultra Addons for Contact Form 7 <= 3.5.50 - Unauthenticated Arbitrary File Upload via Signature Form Field

Published Sep 26, 2026 CVSS 3.1 · 9.8 Critical EPSS 4.3% KEV · Not listed
Description
The Ultra Addons for Contact Form 7 plugin for WordPress is vulnerable to Arbitrary File Upload due to insufficient file type validation in the 'uacf7_wpcf7_mail_components' function in all versions up to, and including, 3.5.50. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible. Note: This is only exploitable when the plugin's PDF Generator module is enabled, which is disabled by default.
