What fixes it

  • 2.12.2MB Custom Post Types & Custom TaxonomiesCVE List

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 MB Custom Post Types & Custom Taxonomies WordPress plugin before 2.12.2 does not perform a capability check or validate a nonce on its migration actions, allowing any authenticated user, such as a subscriber, to trigger a one-way migration that creates published records and permanently deletes a companion MB Custom Post Types & Custom Taxonomies WordPress plugin before 2.12.2's entire post-type and taxonomy configuration.
