At a glance

CVE-2025-14356 is a medium-severity Authorization Bypass Through User-Controlled Key vulnerability in the Ultra Addons for Contact Form 7 WordPress plugin, affecting versions <= 3.5.33. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 3.5.34; sites on affected versions should update now. Disclosed December 2025, reported by shark3y.

Vulnerability Overview

The Ultra Addons for Contact Form 7 plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the 'uacf7_get_generated_pdf' function in all versions up to, and including, 3.5.33. This makes it possible for authenticated attackers, with Subscriber-level access and above, to generate and get form submission PDF, when the "PDF Generator" and the "Database" addons are enabled (disabled by default).

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user.

CWE-639: Authorization Bypass Through User-Controlled Key

Ultra Addons for Contact Form 7 <= 3.5.33 carries this weakness at uacf7_get_generated_pdf, and reaching it takes an account at Subscriber level or above. Authorization bypass through a user-controlled key, often called insecure direct object reference, means the application looks up a record by an identifier from the request without checking that the caller owns it.

Changing a number in the request is enough to read or modify other users' records, which on commerce and membership sites means customer data. For Ultra Addons for Contact Form 7 the fix is 3.5.34: builds <= 3.5.33 are affected, anything from 3.5.34 onward is not.

Remediation

Update to version 3.5.34, or a newer patched version

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Ultra Addons for Contact Form 7 3.5.34 closes this, and updating the plugin is the step that ends it.
