EPSS · scored 2026-10-28

In Ignition 8.1.53 and earlier, the Gateway "Create Project Role(s)" setting shipped blank, which permitted any authenticated user to create projects (if they can execute gateway scripts). Ignition 8.1.54 restricts project creation to Designer sessions and no longer relies on this setting. The 8.3 series is not affected.

    Inductive Automation has determined that this issue is a default-value configuration, not a flaw in the access control itself. The security control enforces exactly what the "Create Project Role(s)" setting specifies; because the setting shipped blank, no role was required to create a project. Populating the setting fully closes the vulnerability.
