CVE-2026-26977
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedFrappe Learning Management System (LMS) is a learning system that helps users structure their content. In versions 2.44.0 and below, unauthorized users are able to access the details of unpublished courses via API endpoints. A fix for this issue is planned for the 2.45.0 release.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Frappe LMS versions 2.44.0 and below contain an information disclosure vulnerability where API endpoints for course data do not properly enforce authorization checks. Unpublished courses that should be restricted to authenticated/authorized users can be accessed by any user, including unauthenticated requests, exposing potentially sensitive educational content.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if Frappe Learning is installedCheck the installed apps in the Frappe bench environment using 'bench get-app list' or review the site's apps list in the Frappe desk under 'Installed Applications'.Affected if Frappe Learning appears in the installed applications list
-
Determine the installed version of Frappe LearningRun 'bench list-apps' or check the apps.json file in your Frappe site, or view the app version in the Frappe desk under 'Installed Applications'. Compare the version number against the affected range (>= 2.0.0 and < 2.45.0).Affected if The installed version is 2.44.0 or below, or any version from 2.0.0 up to but not including 2.45.0
-
Verify if course API endpoints are network-accessibleAttempt to access course-related API endpoints such as /api/method/lms.api.get_courses or /api/method/lms.api.get_course_details from an unauthenticated browser or using a tool like curl without providing authentication headers.Affected if The API endpoints respond with HTTP 200 and return course data without requiring authentication
-
Check for unpublished or restricted courses in the systemLog into the Frappe desk as an administrator, navigate to the LMS module, and review the course list to identify courses marked as 'Draft', 'Private', or with visibility restrictions.Affected if There are unpublished or restricted courses present in the LMS system
-
Confirm unauthorized access to restricted course contentUsing an unauthenticated request (no login cookies or API token), query specific course API endpoints using course IDs from restricted courses and verify if full course content, lessons, or membership data is returned.Affected if Unauthenticated requests successfully retrieve details about courses that should be restricted to authenticated or authorized users only
A system is affected if it runs Frappe Learning version 2.0.0 through 2.44.0 and the course API endpoints are accessible to unauthenticated users, allowing them to view unpublished or restricted course content.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2.45.0
Upgrade to version 2.45.0 when released. Until then, consider restricting network access to API endpoints or implementing proxy-level authentication controls.
2.45.0 or later
- Back up the current Frappe Learning Management System installation and database
- Update the Frappe Learning app to version 2.45.0 or later using bench (e.g., bench get-app [email protected] or bench update)
- Migrate the database if required (bench migrate)
- Verify the fix by confirming that unauthenticated users can no longer access unpublished courses via API endpoints
- Test authenticated users with appropriate permissions can still access unpublished courses they are authorized to view
