Frappe Learning Management System (LMS) is a learning system that helps users structure their content. Prior to version 2.52.1, a remote attacker can request a traversal path handled by SCORMRenderer.render in lms/page_renderers.py. The renderer constructs and opens a server-side path without first confirming that its real path remains within public/scorm, allowing files outside the SCORM directory to be read when they are accessible to the server process.
This issue is fixed in version 2.52.1.
