CVE-2026-72690
HighCVSS 7.1Exploitation Probability (EPSS)

Summary
An improper authorization vulnerability in Attendize through commit 9289acb allows an authenticated remote attacker to inject persistent mandatory survey questions into another organizer's events via the POST /event/{event_id}/question/create endpoint. The postCreateEventQuestion method loads the target event without the tenant-isolation scope, enabling cross-tenant writes; the injected question cannot be removed by the victim.
Risk Assessment
An attacker can manipulate other organizers' events, potentially leading to data integrity issues and process disruption.
Recommendation
Update Attendize to a patched version and implement tenant isolation checks in the postCreateEventQuestion method. Restrict question creation to events owned by the authenticated user.
Original NVD description (English source)
An improper authorization vulnerability in Attendize through commit 9289acb allows an authenticated remote attacker to inject persistent mandatory survey questions into another organizer's events via the POST /event/{event_id}/question/create endpoint. The postCreateEventQuestion method loads the target event without the tenant-isolation scope, enabling cross-tenant writes; the injected question cannot be removed by the victim because the victim's account-scoped delete path cannot resolve a question owned by another tenant.
