CVE-2026-39415Network attack vector

Quiz-result falsification via client-trusted score submission

Published Apr 8, 2026 · Updated Apr 8, 2026

Improper client-side enforcement in Frappe Learning before 2.46.0 allows remote authenticated users to alter their quiz scores. The quiz-submission workflow accepts a score calculated in the browser without independently recomputing or validating it on the server. A student account and access to a quiz are required; manipulation affects that student's result integrity without exposing other accounts or granting additional privileges.
