# WordPress Ultra Addons for Contact Form 7: unauthenticated arbitrary file read

Link for people: https://infrastack.ai/live/CVE-2026-100386 (this .md is for agents)

The Ultra Addons for Contact Form 7 WordPress plugin fails to restrict file paths in its uacf7_wpcf7_mail_components function, up to and including version 3.5.54. An unauthenticated attacker can read arbitrary files on the server, which may contain sensitive information.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check whether the Ultra Addons for Contact Form 7 plugin is installed and its version (`3.5.54` and earlier are listed as affected).
- Check whether the PDF Generator addon is active and whether any contact form has an administrator-configured PDF body template enabled.

## Fix

- Ultra Addons for Contact Form 7 versions after `3.5.54` are the fix range; the exact fixed version is unknown.

## From the sources

The Ultra Addons for Contact Form 7 plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 3.5.54 via the uacf7_wpcf7_mail_components function. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information. Exploitation requires the PDF Generator addon to be active and an administrator-configured PDF body template to be enabled for the targeted contact form.
