Last modified

CVE-2026-72690 is a high-severity vulnerability rated 7.1/10 on the CVSS scale. 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.. EPSS estimates a 0.25% chance of exploitation in the next 30 days.
