CVE-2026-53635

Status: DeferredHigh (7.6)—

Open edX Platform enables the authoring and delivery of online learning at any scale. Prior to commit 59bb6d6, the view function set_course_mode_price() at lms/djangoapps/instructor/views/instructor_dashboard.py:430 is decorated only with @login_required and performs no course-level permission check. Any authenticated user — including a learner account with zero course roles — can issue a single POST request to overwrite the honor mode price and currency of any course on the platform. The companion frontend modal was removed in a prior cleanup, but the URL route and view remain live, making this an unguarded orphan endpoint. This issue has been patched via commit 59bb6d6.
