Administrator-session script execution via retained event handlers
Published Jul 30, 2026 · Updated Jul 30, 2026
Stored XSS in LifterLMS before 10.0.10 allows remote authenticated users to execute JavaScript in an administrator's session. The Featured Pricing Information path retains event-handler attributes in the _llms_featured_pricing course metadata and renders the value without safe output encoding. An Instructor must store the payload, and an administrator must view or interact with the affected pricing field.
