Title
Attendize Attendize - Insecure Direct Object Reference
Summary
An insecure direct object reference vulnerability in Attendize through commit 9289acb allows any authenticated event organiser to bulk import attendees into events belonging to other accounts via the postImportAttendee endpoint. The endpoint loads the target event by ID without verifying ownership against the requesting organiser account. An attacker can inject bulk attendee data into any event in the system regardless of account boundaries.
