LearnHouse before 1.4.0 contains a missing authorization vulnerability in POST /api/v1/playgrounds/{uuid}/duplicate that skips the read-access and draft checks enforced by get_playground. Authenticated users with playground creation rights, such as Instructors, who know a RESTRICTED or unpublished playground UUID can copy its html_content and republish it publicly.
