    WAGO recommends that all affected users with WAGO I/O-PRO/CODESYS 2.3 PLCs update to the firmware and use the latest version of WAGO I/O-Pro as soon as it is available. Until the updates are available, we recommend switching off the CODESYS IP port 2455 after commissioning or, if this not possible, use a strong admin password. ### PFC200 Family | Ord.

  • FSA-202601Several CODESYS vulnerabilities in Festo Automation Suite2026-02-26csaf · festo_psirtDE

    Starting with Festo Automation Suite (FAS) version 2.8.0.138, the suite is delivered only with a connector to Codesys, rather than including Codesys directly. Prior to this version, Codesys was bundled within the FAS installation. From version 2.8.0.138 onwards, customers are required to download and install Codesys independently. This change impacts the handling of security vulnerabilities (CVEs) related to Codesys. Any Codesys-related security issues must now be addressed by the customer through their separate Codesys installation. The FAS itself includes only the connector component, which is maintained and updated within the suite. Please ensure that Codesys is kept up to date independently to mitigate any potential security risks associated with the Codesys software.
