The advisory
The Mapster WP Maps WordPress plugin before 2.0.6 does not perform any authorization check on a REST API route that writes post data, allowing unauthenticated attackers to overwrite the title of arbitrary posts, create arbitrary published posts, and overwrite the Mapster WP Maps WordPress plugin before 2.0.6's stored settings.
