CVE-2026-72546
HighCVSS 7.1Summary
An insecure direct object reference vulnerability in Attendize through commit 9289acb allows any authenticated event organiser to inject attendees and orders into events belonging to other accounts via the postInviteAttendee endpoint. The endpoint loads the target event by ID without scoping the query to the authenticated organiser account. An attacker can modify event data and financial records across account boundaries.
Risk Assessment
The risk includes integrity breach of financial and event data, which can lead to fraudulent orders and financial losses. It may also undermine trust in the system and affect settlements.
Recommendation
It is recommended to immediately apply patches or add event ownership verification in the postInviteAttendee endpoint. Also monitor transactions and event data.
