At a glance

CVE-2024-13869 is a high-severity Unrestricted Upload of File with Dangerous Type vulnerability in the WPvivid WordPress plugin, affecting versions <= 0.9.112. It carries a CVSS score of 7.2 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Admin level or above. The issue is fixed in version 0.9.113; sites on affected versions should update now. Disclosed February 2025, reported by Ryan Kozak.

Vulnerability Overview

The Migration, Backup, Staging – WPvivid Backup & Migration plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the 'upload_files' function in all versions up to, and including, 0.9.112. This makes it possible for authenticated attackers, with Administrator-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible. NOTE: Uploaded files are only accessible on WordPress instances running on the NGINX web server as the existing .htaccess within the target file upload folder prevents access on Apache servers.

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. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-434: Unrestricted Upload of File with Dangerous Type

WPvivid <= 0.9.112 carries this weakness at upload_files, and reaching it takes an account at Admin level or above. 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 WPvivid the fix is 0.9.113: builds <= 0.9.112 are affected, anything from 0.9.113 onward is not.

Remediation

Update to version 0.9.113, or a newer patched version

How does WordSec protect against this?

An attacker needs Admin access first, so the firewall sees the attempt as traffic from a logged-in account: 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: WPvivid 0.9.113 closes this, and updating the plugin is the step that ends it.
