## Description

The MapSVG plugin for WordPress is vulnerable to Sensitive Information Exposure via the /mapsvg/v1/posts REST route in all versions up to, and including, 8.16.1. This is due to the route's permission callback always returning true and the query returning post_content for published posts without excluding password-protected ones. This makes it possible for unauthenticated attackers to read the content of password-protected posts.
