Stored XSS in JetEngine WordPress Plugin

Publication date: 2026-08-19

Last updated on: 2026-08-19

Assigner: WPScan

Description
The JetEngine WordPress plugin before 3.8.14 adds SVG to the site-wide list of allowed upload types without sanitising the file contents, allowing users with the upload files capability, such as Authors, to upload a file containing malicious JavaScript that executes in the browser of any user who opens it (Stored Cross-Site Scripting). On multisite, this also overrides an upload-type restriction set by the network administrator.

Executive Summary

This is a stored cross-site scripting (XSS) vulnerability in the JetEngine WordPress plugin before version 3.8.14. It allows users with upload capabilities, like Authors, to upload SVG files containing malicious JavaScript. The plugin does not sanitize SVG file contents, so the JavaScript executes when the file is opened in a browser.

Detection Guidance

Check if the JetEngine WordPress plugin version is below 3.8.14. Inspect uploaded SVG files for embedded JavaScript or suspicious content. Review user roles with upload capabilities, such as Authors, for unauthorized file uploads.

Impact Analysis

An attacker could upload a malicious SVG file that executes JavaScript when viewed by any user. This could lead to unauthorized actions on behalf of users, data theft, or defacement of the website. On multisite installations, it bypasses network administrator upload restrictions.

Compliance Impact

This vulnerability could lead to unauthorized access to user data, violating GDPR and HIPAA requirements for data protection and access controls. It may result in non-compliance due to potential data breaches or unauthorized data exposure.

Mitigation Strategies

Update the JetEngine plugin to version 3.8.14 or later immediately. Remove any untrusted SVG files from the system. Restrict file upload capabilities to only necessary user roles. Monitor for unusual activity or unauthorized file uploads.
