Technical details
The plugin fails to properly check whether an event has a public attendee list enabled before returning attendee details via the single attendee REST API endpoint. An unauthenticated attacker can exploit this via an HTTP request to retrieve attendee names from events configured with private attendee lists, bypassing the intended access control mechanism.
