What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

The MetForm WordPress plugin before 4.3.1 does not properly restrict access to form submission data, allowing unauthenticated attackers to view submitter information through the REST API.
