Executive Summary

This is a Stored Cross-Site Scripting (XSS) vulnerability in the MapSVG plugin for WordPress. It allows an attacker to inject malicious scripts into web pages that are stored on the server and executed when other users view those pages. The flaw exists due to improper neutralization of user input during web page generation.

Detection Guidance

To detect this vulnerability, inspect MapSVG installations for versions up to 8.16.1. Check web application logs for unusual input patterns or script tags in map data. Use tools like OWASP ZAP or Burp Suite to scan for stored XSS vulnerabilities in interactive maps.

Impact Analysis

An attacker could exploit this to steal user session cookies, redirect users to malicious sites, or perform actions on their behalf. Users with access to edit or create maps could be targeted, and visitors viewing those maps may have their data compromised.

Compliance Impact

This vulnerability could lead to unauthorized access to user data, violating GDPR's data protection requirements. For HIPAA, it may expose protected health information if user sessions or data are compromised. Organizations must address this to maintain compliance.

Mitigation Strategies

Immediately update MapSVG to the latest version beyond 8.16.1. If an update is unavailable, disable the vulnerable component or restrict user input to prevent script injection. Apply input validation and output encoding to sanitize map data.
