WP Go Maps (formerly WP Google Maps) < 9.0.29 - Unauthenticated Reflected Cross-Site Scripting

Description

The plugin is vulnerable to Reflected Cross-Site Scripting via the map id parameter due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
