Summary
The WP Verify API WordPress plugin through 1.0.0 does not have any authorisation check in one of its REST routes, allowing unauthenticated users to insert arbitrary data into its own database table, as well as to make the site send templated verification emails to arbitrary email addresses. The route is not rate limited either.
