{"id":"CVE-2026-61805","kind":"vulnerability","aliases":["CVE-2026-61805"],"related":[],"title":"Frappe LMS: students can forge passing quiz results and certificates","description":"Frappe Learning Management System (LMS) is a learning system that helps users structure their content. Prior to version 2.54.0, quiz submission records are not adequately authorized on the server. Through a `REST` bypass, an authenticated student can record a passing or perfect quiz result without their answers being verified, unlocking course completion and certificates. The student can also create a submission attributed to another user, exhausting that user's allowed attempts and blocking legitimate submissions. These integrity and availability issues are scoped to quiz results; they do not expose other users' data or grant elevated roles. This issue is fixed in version 2.54.0.","summary":"Frappe Learning Management System before 2.54.0 does not check quiz submissions on the server, so a logged-in student can record a passing or perfect quiz score without answering. A student can also file quiz attempts under another user's account, using up that user's attempts.","severity":"medium","cvss":5.3,"epss":null,"exploited":false,"exploited_at":null,"products":[],"ecosystems":[],"tags":["education","frappe-lms","package","self-hosted"],"not_affected_if":["no-certificates","no-quizzes","version-2.54.0-or-later"],"how_to_check":"- Check the installed Frappe LMS version in the app's `package.json` or via the bench app list; versions below `2.54.0` are affected.\n- Confirm whether the site lets students take quizzes and issues certificates on completion.","fix":"- Frappe LMS: upgrade to `2.54.0` or later.","status":"open","published_at":"2026-10-30T17:17:27+00:00","first_seen_at":"2026-10-30T17:31:39+00:00","triaged_at":"2026-10-30T17:32:15+00:00","updated_at":"2026-10-30T17:32:15+00:00","category":"package","confidence":0.7,"triage":{"at":"2026-10-30T17:32:15Z","model":"claude-haiku-5-5","output":{"fix":"- Frappe LMS: upgrade to `2.54.0` or later.","reach":"internet","title":"Frappe LMS: students can forge passing quiz results and certificates","impact":"low","summary":"Frappe Learning Management System before 2.54.0 does not check quiz submissions on the server, so a logged-in student can record a passing or perfect quiz score without answering.
