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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-862"],"vendors":[],"products":[],"references":[{"url":"https://github.com/frappe/lms/commit/876504f3900512f528b6e4a7bd3a15673eedd386","tags":[]},{"url":"https://github.com/frappe/lms/security/advisories/GHSA-4566-2phx-68gh","tags":[]},{"url":"https://github.com/frappe/lms/tree/v2.54.0","tags":[]}],"exploitRefs":[{"url":"https://github.com/frappe/lms/commit/876504f3900512f528b6e4a7bd3a15673eedd386","tags":[]},{"url":"https://github.com/frappe/lms/security/advisories/GHSA-4566-2phx-68gh","tags":[]},{"url":"https://github.com/frappe/lms/tree/v2.54.0","tags":[]}],"hasPoc":true,"ai":null}
