CVE-2026-77393: CWE-276 in Inductive Automation Ignition
Description
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.

Technical Analysis
In Inductive Automation Ignition versions 8.1.53 and earlier, the Gateway "Create Project Role(s)" setting was improperly configured as blank by default. This misconfiguration permitted any authenticated user capable of executing gateway scripts to create projects, violating intended access controls. The vulnerability is classified under CWE-276 (Incorrect Default Permissions). Starting with version 8.1.54, project creation is restricted to Designer sessions, removing reliance on the vulnerable setting. The 8.3 series is confirmed not vulnerable.
Potential Impact
An attacker with authenticated access and the ability to execute gateway scripts could create projects without proper authorization, potentially leading to unauthorized control or manipulation of the system. The CVSS score of 8.8 reflects high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
Upgrade to Ignition version 8.1.54 or later, where project creation is restricted to Designer sessions and the vulnerable setting is no longer used. No other official remediation or temporary fixes are documented. Patch status is not explicitly confirmed in the vendor advisory; however, the description indicates version 8.1.54 addresses the issue.
