CISA warned that two critical PowerSYSTEM Center flaws (CVSS 9.0) could let authenticated users access administrator resources or execute unauthorized database commands, affecting energy and manufacturing sectors worldwide. The agency released advisory ICSA-26-307-01 on November 3, 2026. CISA credited Chinmay Patel of Digital Boundary Group and Subnet Solutions with reporting the vulnerabilities. The Canadian vendor has provided upgrade guidance and temporary measures for organizations that cannot immediately update affected systems. The first flaw, CVE-2026-63017, involves incorrect authorization , tracked as CWE-863. A user with limited permissions can access resources normally reserved for administrators. In simple terms, signing in with a basic account does not keep the user within the access limits intended for that account. CISA Warns Critical Flaws in PowerSYSTEM Center The second flaw, CVE-2026-63774, is an SQL injection vulnerability tracked as CWE-89 . Insufficient input checks in the report designer allow an authenticated user to execute unauthorized SQL commands. The disclosed impact concerns database commands, not confirmed operating system code execution. Both CVSS vectors describe low attack complexity, low privileges, and no required user interaction. They specify an adjacent attack vector rather than unrestricted network access. CISA states that these vulnerabilities are not remotely exploitable and that no known public exploitation had been reported when the advisory was released. CVE-2026-63017 affects PowerSYSTEM Center 2020 versions through 5.29.x, PowerSYSTEM Center 2024 versions 6.0.x through 6.2.x, and PowerSYSTEM Center 2026 versions 7.0.x through 7.1.x. CVE-2026-63774 affects the listed 2024 and 2026 ranges. The advisory does not list the 2020 branch as affected by SQL injection. Subnet Solutions recommends PowerSYSTEM Center 2020 Update 30 for affected 2020 installations. Organizations running the 2024 branch should upgrade to PowerSYSTEM Center 2026 Update 1.1. Existing 2026 installations should also update to Update 1.1, according to CISA’s machine-readable advisory. Checking installed versions is therefore essential before planning upgrades. Cybersecurity News previously covered CISA’s OT asset inventory guidance , which explains how accurate device and software records support vulnerability management across industrial environments. For organizations unable to update, Subnet recommends monitoring user activity records and restricting Client Access Server users’ access to browser F12 Developer Tools to reduce authorization-related risk. For the SQL injection issue, the vendor recommends restricting user access to the report designer. These are interim measures, not replacements for the recommended updates. CISA also advises keeping control systems off the public internet, placing them behind firewalls, and separating them from business networks. Where remote access is necessary, organizations should use updated VPNs and assess connected devices. Related secure OT connectivity guidance explains the value of limited exposure and controlled connections. Before applying changes, operators should assess operational impact and risk. Operators should follow internal response procedures for suspected malicious activity and report it to CISA. Give your SOC the alert context to stops incidents quickly.

CISA warned that two critical PowerSYSTEM Center flaws could enable unauthorized administrator access and database command execution.

Incorrect authorization in PowerSYSTEM Center allows a low-privileged, authenticated user to access resources normally limited to administrators.

Insufficient input validation in the PowerSYSTEM Center report designer allows an authenticated user to execute unauthorized SQL commands.

TL;DR CISA warns of two critical bugs in Subnet Solutions PowerSYSTEM Center. Both CVE-2026-63017 and CVE-2026-63774 carry a high 9.0 score. Consequently, local attackers can bypass access rules. They can also run rogue database code. Why It Matters Subnet Solutions PowerSYSTEM Center helps power plants run grid gear. According to the CISA ICSA-26-307-01 advisory, firms use this tool in energy plants worldwide.

PowerSYSTEM Center does not correctly check a user’s rights, so a user with limited permissions can view or change settings that should be reserved for.

The report design feature in PowerSYSTEM Center does not properly check the information it receives, so a user who is signed in can trick it into sending.

Subnet Solutions reported these vulnerabilities to CISA. Recommended Practices CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. 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.
