Vulnerability Advisory : Advanced Twenty Seventeen <= 1.3.1 - Subscriber+ Site Theme Switch via ats_create_child_theme with LOW Attack Complexity

The Advanced Twenty Seventeen WordPress plugin through 1.3.1 does not perform any capability or nonce check on the action that creates and activates its bundled child , allowing any authenticated user such as a subscriber to switch the site's active site-wide, and allowing the same action to be triggered against any logged-in user including an administrator via CSRF.
