EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.7 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.7%, top 50% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
