Recommendation: Plan a near-term fix — a public PoC already exists.
The Cornerstone WordPress plugin before 7.8.8 does not enforce capability checks on one of its CSS-preview request handlers, and exposes the nonce needed to call it to every logged-in user on any wp-admin page, allowing any authenticated user to evaluate dynamic content tokens against arbitrary users and disclose their sensitive metadata including raw password hashes. This affects the premium co Cornerstone page builder distributed bundled with the X , not the unrelated free `cornerstone` Cornerstone WordPress plugin before 7.8.8 (v0.8.x) on the .org repository.
