What is CVE-2026-77226?
CVE-2026-77226 is a critical missing authorization vulnerability in Camunda 7, published on 5 Oct 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
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.
Weakness: CWE-863
