VG WORT METIS <= 2.0.0 - Missing Authorization to Authenticated (Subscriber+) Limited Settings Update

The VG WORT METIS plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the gutenberg_save_post() function in all versions up to, and including, 2.0.0. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update limited post settings.
