Technical details
A stored Cross-Site Scripting (XSS) vulnerability exists in LifterLMS versions prior to 10.0.10. The root cause is insufficient sanitization of the 'Featured Pricing Information' field, which fails to strip HTML event-handler attributes (e.g., onclick) before storing them in the _llms_featured_pricing meta. An attacker with 'Instructor' or higher privileges can inject a payload that executes when an administrator views the course in the WordPress editor or when a user interacts with the field on the public catalog page. This can lead to session hijacking or unauthorized administrative actions. The issue is resolved in version 10.0.10.
