Executive Summary

This vulnerability affects the Elementor Website Builder WordPress plugin versions before 4.3.5. Users with Author role or higher can upload SVG files containing malicious JavaScript. These files are not properly sanitized during upload, allowing stored cross-site scripting (XSS) when opened by other users. Exploitation requires unfiltered file uploads to be enabled in plugin settings, which is not the default.

Detection Guidance

Check if your Elementor plugin version is below 4.3.5 by inspecting the plugin files or WordPress admin panel. Look for unauthorized SVG uploads in the WordPress media library or server uploads directory. Review user roles with Author permissions or higher for unusual activity.

Impact Analysis

An attacker could upload a malicious SVG file that executes JavaScript in the browser of any user who views it. This could lead to unauthorized actions, data theft, or account compromise for users with access to the affected WordPress site.

Compliance Impact

This vulnerability could lead to unauthorized access or data breaches, potentially violating GDPR (data protection) or HIPAA (health information privacy) requirements. Organizations may face compliance penalties if user data is compromised due to this issue.

Mitigation Strategies

Update Elementor to version 4.3.5 or later immediately. Disable unfiltered file uploads in Elementor settings if enabled. Remove any suspicious SVG files from the media library and server. Audit user roles to ensure only necessary permissions are assigned.
