At a glance

CVE-2025-14800 is a high-severity Unrestricted Upload of File with Dangerous Type vulnerability in the Redirection for Contact Form 7 WordPress plugin, affecting versions <= 3.2.7. It carries a CVSS score of 8.1 (reachable over the network; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 3.2.8; sites on affected versions should update now. Disclosed December 2025, reported by LionTree.

Vulnerability Overview

The Redirection for Contact Form 7 plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the 'move_file_to_upload' function in all versions up to, and including, 3.2.7. This makes it possible for unauthenticated attackers to copy arbitrary files on the affected site's server. If 'allow_url_fopen' is set to 'On', it is possible to upload a remote file to the server.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, and no privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-434: Unrestricted Upload of File with Dangerous Type

Redirection for Contact Form 7 <= 3.2.7 carries this weakness at move_file_to_upload, and reaching it takes no account at all. An unrestricted file upload lets a caller store a file whose type or destination the application does not properly constrain.

If an uploaded file lands anywhere the server will execute, the flaw becomes remote code execution and the site should be treated as fully compromised. For Redirection for Contact Form 7 the fix is 3.2.8: builds <= 3.2.7 are affected, anything from 3.2.8 onward is not.

Remediation

Update to version 3.2.8, or a newer patched version

How does WordSec protect against this?

Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. None of that substitutes for the fix: Redirection for Contact Form 7 3.2.8 closes this, and updating the plugin is the step that ends it.
