At a glance

CVE-2025-4367 is a medium-severity Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS) vulnerability in the Download Manager WordPress plugin, affecting versions <= 3.3.18. It carries a CVSS score of 6.4 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Author level or above. The issue is fixed in version 3.3.19; sites on affected versions should update now. Disclosed June 2025, reported by Brian Sans-Souci (liardom).

Vulnerability Overview

The Download Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's wpdm_user_dashboard shortcode in all versions up to, and including, 3.3.18 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

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-80: Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS)

The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special characters such as <, >, and & that could be interpreted as web-scripting elements when they are sent to a downstream component that processes web pages.

Remediation

Update to version 3.3.19, or a newer patched version

How does WordSec protect against this?

An attacker needs Author 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. None of that substitutes for the fix: Download Manager 3.3.19 closes this, and updating the plugin is the step that ends it.
