At a glance

CVE-2024-39639 is a medium-severity Missing Authorization vulnerability in the Iptanus File Upload WordPress plugin, affecting versions <= 4.24.7. It carries a CVSS score of 5.4 (reachable over the network; low attack complexity). The root cause is a missing authorization check on a reachable function. The issue is fixed in version 4.24.8; sites on affected versions should update now. Disclosed August 2024, reported by emad.

Vulnerability Overview

The WordPress File Upload plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on the wfu_ajax_action_save_shortcode() function in versions up to, and including, 4.24.7. This makes it possible for authenticated attackers, with contributor-level access and above, to save shortcodes

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-862: Missing Authorization

Iptanus File Upload <= 4.24.7 carries this weakness at wfu_ajax_action_save_shortcode(), and reaching it takes a caller who can reach the endpoint. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.

Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Iptanus File Upload the fix is 4.24.8: builds <= 4.24.7 are affected, anything from 4.24.8 onward is not.

Remediation

Update to version 4.24.8, 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: Iptanus File Upload 4.24.8 closes this, and updating the plugin is the step that ends it.
