WP Google Map < 1.7.7 - Authenticated Stored Cross-Site Scripting (XSS)

Description

The plugin did not sanitise or escape the Map Title before outputting them in the page, leading to a Stored Cross-Site Scripting issue by high privilege users, even when the unfiltered_html capability is disallowed

Proof of Concept

Create a new map.
Add an XSS payload to the title.
Click "Show as map title".
Add the map to a page or post with the shortcode. 

Affects Plugins
