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
MitigationInductive 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. MitigationInductive 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.https://docs.inductiveautomation.com/docs/8.1/platform/security/gatewa

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.
CISA also recommends users take the following measures to protect themselves from social engineering attacks: Do not click web links or open attachments in unsolicited email messages. Refer to Recognizing and Avoiding Email Scams for more information on avoiding email scams. Refer to Avoiding Social Engineering and Phishing Attacks for more information on social engineering attacks. No known public exploitation specifically targeting this vulnerability has been reported to CISA at this time.
