CVE-2025-14478 is a high-severity Improper Restriction of XML External Entity Reference vulnerability in the Demo Importer Plus WordPress plugin, affecting versions <= 2.0.9. It carries a CVSS score of 7.5 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires no authentication.

Vulnerability Overview

The Demo Importer Plus plugin for WordPress is vulnerable to XML External Entity Injection (XXE) in all versions up to, and including, 2.0.9 via the SVG file upload functionality. This makes it possible for authenticated attackers, with Author-level access and above, to achieve code execution in vulnerable configurations. This only impacts sites on versions of PHP older than 8.0.

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 privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on confidentiality.

CWE-611: Improper Restriction of XML External Entity Reference

The product processes an XML document that can contain XML entities with URIs that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output.

Remediation

Update to version 2.0.10, 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: Demo Importer Plus 2.0.10 closes this, and updating the plugin is the step that ends it.
