Nimble Builder <= 3.3.8 - Subscriber+ Non-Public Content Disclosure via sek_get_nimble_content_for_seo_plugins

The Nimble Page Builder WordPress plugin through 3.3.8 does not perform an authorization check when returning page-builder content through an authenticated AJAX action, allowing any authenticated user (Subscriber+) to disclose the page-builder content of arbitrary non-public (draft, pending, private, scheduled) posts and pages.
