Payment validation bypass in Frappe LMS 2.51.0 and earlier lets an authenticated user enroll in paid courses for free by supplying an unrelated batch that was never linked to the target course, granting access to premium content without completing payment. The flaw is an authorization/business-logic weakness (CWE-288) fixed in version 2.52.0, which now verifies the batch belongs to the course before enrollment. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.

DescriptionCVE.org
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.
Executive ViewAI
Frappe LMS versions 2.51.0 and earlier contain a payment validation bypass that allows authenticated users to enroll in paid courses for free, directly impacting revenue collection and granting unauthorized access to premium educational content. While no public exploit has been identified at time of analysis, the authorization flaw presents significant financial and access control risk for organizations operating paid learning platforms. Immediate identification and patching of affected deployments is essential to prevent potential revenue loss and unauthorized access to premium courseware.
Within 24 hours, inventory all Frappe LMS deployments and identify instances running version 2.51.0 or earlier, assessing exposure in terms of affected paid courses and user populations. Within 7 days, upgrade all vulnerable Frappe LMS instances to version 2.52.0, which implements authorization verification to ensure batches are properly linked to courses before enrollment. Within 30 days, complete full regression testing and validation of the patch across all production environments to confirm no disruptions to enrollment workflows.
Apply vendor patch.
