What it is

The Cornerstone WordPress plugin before 7.8.9 does not enforce capability checks on one of its REST API routes, allowing any authenticated user to disclose the metadata of any other user, including roles, session token previews and stored billing/shipping fields. This affects the premium co Cornerstone page builder distributed bundled with the X , not the unrelated free `cornerstone` Cornerstone WordPress plugin before 7.8.9 (v0.8.x) on the .org repository.
