Peach Payments Gateway <= 3.1.9 is vulnerable to Broken Access Control vulnerability

The Peach Payments Gateway plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the peach_core_version_rollback() function in versions up to, and including, 3.1.9. This makes it possible for authenticated attackers, with subscriber-level access and above, to rollback the plugin's version.
