Summary
fossasia eventyay-exhibition through commit f68888e contains an authorization bypass in its exhibitor lead creation API. The API accepts a user-controlled key, such as another event's pseudonymization id or order secret, without checking that it belongs to the organizer named in the URL (CWE-639). An exhibitor with lead scanning enabled can read other organizers' attendee names, emails, addresses and answers.
