Upgrade Fiber Admin to version 4.0.1 or later, where the missing authorization checks have been implemented. No other mitigation is indicated or required as the issue is addressed by this official fix.
Description
The Fiber Admin WordPress plugin versions before 4.0.1 lack authorization checks in certain AJAX actions. This flaw allows unauthenticated users to reorder arbitrary posts, including drafts, private posts, and navigation menu items, as well as taxonomy terms if term ordering is enabled. The issue is fixed in version 4.0.1.
