The GMap Generator plugin for WordPress contains a vulnerability that allows for Stored Cross-Site Scripting through inadequate sanitization of the 'h' parameter. This issue affects all versions up to and including 1.1. Authenticated users with Contributor-level access can exploit this vulnerability to inject malicious scripts into web pages, which will execute in the browsers of users who visit the compromised pages.
