What is CVE-2026-53635?
CVE-2026-53635 is a high-severity missing authorization vulnerability in openedx-platform, published on 2 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
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.
