CVE-2026-54343: Frappe Lms

High severity, CVSS 8.7. EPSS: 0.7% chance of exploitation in the next 30 days.

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.

Affected products

• Frappe Lms: before 2.52.1 (fixed in 2.52.1)
