CVE-2026-77226

CVE-2026-77226 is a high-severity vulnerability rated 8.1/10 on the CVSS scale. Camunda 7.24.0 before 7.24.15 contains an incorrect authorization vulnerability in the Admin web application's first-run setup endpoint, where SetupResource incorrectly determines setup availability by counting only direct members of the camunda-admin group rather than recognizing all configured administrators. An unauthenticated remote attacker can exploit this logic flaw to call the setup user-create endpoint and create a new administrator account when the camunda-admin group is empty but the system is fully administered, resulting in account takeover and potential process deployment or script execution as the engine's service user.. EPSS estimates a 0.69% chance of exploitation in the next 30 days.
