The following versions of Inductive Automation Ignition are affected:
- Ignition <=8.1.53 (CVE-2026-77393)
| CVSS | Vendor | Equipment | Vulnerabilities |
|---|---|---|---|
| v3 8.8 | Inductive Automation | Inductive Automation Ignition | Incorrect Default Permissions |
Background
- Critical Infrastructure Sectors: Critical Manufacturing, Energy, Information Technology
- Countries/Areas Deployed: Worldwide
- Company Headquarters Location: United States
Vulnerabilities
CVE-2026-77393
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.

Remediations
Mitigation
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.
Mitigation
Inductive Automation recommends users upgrade to 8.1.54 or later (or the latest 8.3 version), which restricts project creation to Designer sessions and no longer relies on this setting. Users who must remain on an earlier 8.1 version can fully remediate the issue by setting "Create Project Role(s)" to match their Designer Role. Once the setting is populated, only users holding that role can create projects. See Gateway General Security Settings.

Recommended Practices
CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability. Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet. Locate control system networks and remote devices behind firewalls and isolating them from business networks. When remote access is required, use more secure methods, such as virtual private networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as the connected devices.
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets.
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies.
Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.
