Input validation vulnerability in WP Go Maps (formerly WP Google Maps) 9.0.38

The WP Go Maps plugin, previously known as WP Google Maps, has a security vulnerability in versions 9.0.38 and below. This vulnerability allows attackers with contributor-level permissions or higher, who have been given explicit permission by an administrator, to insert harmful code into pages. This code will then be executed whenever a user accesses the affected page. Version 9.0.39 has added a warning for administrators to be cautious when granting permissions to lower-level users.
