CVE-2026-72690

Attendize Attendize - Cross-Tenant Authorization Bypass

Published Aug 10, 2026 CVSS 3.1 · 5.4 Medium EPSS < 1% KEV · Not listed
Description
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.
