Geo Mashup < 1.13.20 - Missing Authorization to Unauthenticated Plugin Settings Disclosure via 'geo_mashup_content' Parameter

Description

The Geo Mashup plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.13.19. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to expose sensitive plugin configuration data, including Google Maps API keys and GeoNames service credentials, to unauthenticated attackers.
