Inductive Automation Ignition
CISA reports a permissions flaw (CVE-2026-77393, CVSS 8.8) in Inductive Automation Ignition <=8.1.53 letting authenticated users create projects; fixed in 8.1.54.
CISA republished Inductive Automation's advisory for CVE-2026-77393, an incorrect default permissions issue (CWE-276) in Ignition 8.1.53 and earlier. The Gateway "Create Project Role(s)" setting shipped blank, allowing any authenticated user who can execute gateway scripts to create projects. Ignition 8.1.54 restricts project creation to Designer sessions and the 8.3 series is unaffected. CISA notes no known public exploitation of this vulnerability.
- CVSS 3.1 base score of 8.8 (HIGH) with network vector and low privileges required
- Fix: upgrade to Ignition 8.1.54 or use the unaffected 8.3 series
- CISA recommends isolating control systems and minimizing internet exposure
- No public exploitation reported to CISA at this time

|---|---|---|---|---|---|---|---|
| CVE-2026-77393 | Incorrect default permissions in Inductive Automation Ignition 8.1 allow unauthorized project creation Ignition 8.1.53 and earlier shipped with the Gateway's "Create Project Role(s)" setting blank, so the role restriction it was meant to enforce was not applied (CWE-276, incorrect default permissions). An attacker needs network access and a low-privilege authenticated account that can execute gateway scripts; with those, a project-creation request against the Gateway succeeds without requiring Designer access. By creating a project, the attacker can gain high-impact access to the gateway per its CVSS 4.0 score of 8.7 (high confidentiality, integrity, and availability impact), making this useful as a foothold in OT/SCADA environments. All Ignition 8.1 deployments at or below 8.1.53 are affected; 8.1.54 restricts project creation to Designer sessions and the 8.3 series is not affected. There is no known public proof-of-concept, the flaw is not in CISA KEV, and EPSS puts 30-day exploitation probability at 0.5% (42nd percentile). Do: Upgrade Ignition 8.1 to 8.1.54 or later, which restricts project creation to Designer sessions. As an interim mitigation, set the Gateway "Create Project Role(s)" setting to a restricted role and review which authenticated users have gateway script execution rights. Audit existing projects for any unexpected creations made by non-Designer users. | 8.7 | <1% |

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.

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.
