Summary
The Solace Extra WordPress plugin before 1.6.1 does not perform capability checks in several of its AJAX actions and exposes the nonce that protects them on admin pages reachable by low-privileged users, allowing users with a role as low as Subscriber to modify site-wide presentation settings and delete imported site-builder content.
