Check if you are vulnerable description
openedx-platform versions before ulmo can expose a template-rendering route that reflects unescaped query values into LMS or CMS pages. An unauthenticated attacker can run browser-side code in a victim's Open edX session if the victim follows a crafted link.
mitigation
Upgrade openedx-platform to >= ulmo or later.
fixed in >= ulmo
