At a glance
CVE-2025-6997 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the ThemeREX Addons WordPress plugin, affecting versions <= 2.35.1.1. It carries a CVSS score of 6.4 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Contributor level or above. The issue is fixed in version 2.35.2.2; sites on affected versions should update now. Disclosed July 2025, reported by stealthcopter.
Vulnerability Overview
The ThemeREX Addons plugin for WordPress is vulnerable to Stored Cross-Site Scripting via SVG File uploads in all versions up to, and including, 2.35.1.1 due to insufficient input sanitization and output escaping. The plugin’s SVG rendering routine calls the trx_addons_get_svg_from_file() function on an unvalidated 'svg' parameter supplied via the shortcode or Elementor widget settings, then outputs it via the trx_addons_show_layout() function. Because there is no check on the URL’s origin, scheme, or the SVG content itself, authenticated attackers, with Contributor-level access and above, can supply a remote SVG and inject arbitrary web scripts in pages that will execute whenever a user accesses the SVG file.
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-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
ThemeREX Addons <= 2.35.1.1 carries this weakness at svg, and reaching it takes an account at Contributor level or above. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.
Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For ThemeREX Addons the fix is 2.35.2.2: builds <= 2.35.1.1 are affected, anything from 2.35.2.2 onward is not.
Remediation
Update to version 2.35.2.2, or a newer patched version
How does WordSec protect against this?
An attacker needs Contributor 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: ThemeREX Addons 2.35.2.2 closes this, and updating the plugin is the step that ends it.
