## Affected

- iandunn Basic Google Maps Placemarks: through 1.10.7

## Description

The Basic Google Maps Placemarks plugin for WordPress is vulnerable to authorization bypass in versions up to, and including, 1.10.7. 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 modify stored map latitude and longitude options.
