MapGeo Interactive Geo Maps Reflected Cross-Site Scripting Vulnerability

A reflected cross-site scripting vulnerability has been identified in the MapGeo - Interactive Geo Maps plugin for WordPress, affecting all versions through 1.6.27. The issue arises from inadequate input sanitization and output escaping, allowing unauthenticated attackers to inject arbitrary web scripts via the 'map' parameter in the display-map shortcode. These injected scripts can execute on pages if a user is tricked into interacting with a link.

Impact

Exploitation of this vulnerability allows for reflected cross-site scripting, where an attacker can inject scripts that are executed in the context of the user's browser.

Reproduction

To reproduce this vulnerability, use the display-map shortcode and include a 'map' parameter with a value that is not a URL. The injected script will execute if the user clicks on the link.

Remediation

Users are advised to update the MapGeo - Interactive Geo Maps plugin to version 1.6.28 or later.
