Mapster WP Maps: Missing authorization in REST API allows post modification
The Mapster WP Maps WordPress plugin before version 2.0.6 has a REST API route that writes post data without any authorization check. An unauthenticated remote attacker can overwrite the title of arbitrary posts, create published posts and change the plugin's stored settings. The attack requires no login, so any reachable WordPress site running an affected version is exposed.
