- frappe lms: through 2.51.0

## Description

Frappe LMS is an open source learning management system. In version 2.51.0 and earlier, a user could bypass payment validation for courses by using unrelated batch. This has been patched in 2.52.0 with enrollment now validating that the batch is linked to course.
