CVE-2026-82901

CRITICAL 9.8EPSS 4.33%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (4.33%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

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.
