CVE-2026-54343
HIGH 8.7 ALL-YEARSFrappe 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.
Severe if exploited (CVSS 8.7), but no confirmed exploitation. Patch on a normal cadence.
