What is CVE-2026-77226?

An incorrect authorization flaw in the Camunda Admin web application's first-run setup endpoint allows an unauthenticated remote attacker to exploit the system when the camunda-admin group is empty. The vulnerability arises from the SetupResource's failure to accurately assess setup availability, counting only direct group members instead of recognizing all configured administrators. This misconfiguration can lead to unauthorized creation of an administrator account, enabling attackers to potentially deploy processes or execute scripts with administrative privileges.

Affected Version(s)

Camunda 7 7.24.0 < 7.24.15

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
