Overview

CVE-2026-72690 is a high-severity vulnerability. It was published on August 10, 2026 and has a CVSS 3.1 base score of 7.1 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.1, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
