What it means for a small business
If your business uses CODESYS Gateway Server V2, install the vendor's update. If you're not sure whether you use it, ask whoever manages your computers.
How likely is an attack? The Exploit Prediction Scoring System, run by FIRST (the global association of security response teams), puts the odds of this one being exploited in the next 30 days at 1.3%, higher than 71% of CVEs. That’s above average: worth scheduling this week. Scored October 28, 2026, updated daily.
