What it is

A file name from the request can climb out of the intended folder with sequences like ../, reaching files the service never meant to expose.

How it is reached

An attacker can exploit it over the network, without an account, and nobody has to click anything.

What an attacker gains

A successful attack can read the data it protects. In practice, this kind of flaw lets an attacker read or write files outside the folders the service meant to expose.

Is it being exploited?

There is no public report of exploitation yet. It can be exploited automatically, at scale.

What to do

No fixed version is listed yet. Find every place themefic Ultra Addons for Contact Form 7 runs, watch the references for a fix, and plan a replacement if it is no longer supported.
While there is no fix, keep it off the internet or behind a VPN, allowlist or authenticating proxy.

Description from NVD

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.

What this means for your architecture.

A CVE names a product. Whether it matters depends on where that product sits in your systems: what reaches it, which trust boundary it guards and what it can reach once compromised. Veriom maps your components, their relationships and your trust boundaries from your code, cloud and delivery evidence, so you can see where a component like this sits. The radar itself does not look at your systems.

Components it touches

WordPress sites and their plugins. Plugins run inside the site with its database access, and many sites are public.
File storage the service can read or write. The flaw sits between the application and the file system it can reach.

Trust boundaries in play

Internet-facing entry points. No account is needed. Any instance reachable from outside your perimeter, through a load balancer, gateway, VPN or exposed admin port, is in scope.
Between the application and the file system it can reach. An attacker who crosses it can read or write files outside the folders the service meant to expose.
