What is CVE-2026-61803?

The Frappe Learning Management System (LMS) contains a vulnerability in its course certificate checkout flow, which allows authenticated users to manipulate pricing. Prior to the release of version 2.52.1, users could complete transactions for courses or certificates at amounts different from the actual prices due to insufficient validation of client-provided pricing data. This weakness could lead to potential financial losses, although it does not compromise user data or grant unauthorized access. The issue has been resolved in version 2.52.1.

Affected Version(s)

lms < 2.52.1
