CVE-2026-109564 Details
Description
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 Authenticated users with playground creation rights, such as Instructors, who know a RESTRICTED or unpublished playground UUID can copy its html_content and republish it publicly.
A missing authorization vulnerability has been identified in LearnHouse versions prior to 1.4.0. The issue resides in the POST /api/v1/playgrounds/{uuid}/duplicate endpoint, where the authorization checks for read-access and draft status are bypassed. This vulnerability allows authenticated users with the ability to create playgrounds, such as Instructors, to duplicate the content of RESTRICTED or unpublished playgrounds by using their UUIDs. The duplicated content can then be republished publicly.
Users can update to LearnHouse version 1.4.0 or later, where this vulnerability has been addressed.
