    CODESYS GmbH strongly recommends only opening projects from trustworthy sources! If the following dialog appears when opening a project, please pay attention to this warning and do not try to load the affected project: "The project file is corrupt. Would you still like to try to load the project? Attention! CODESYS could become unstable when loading a corrupt project file." In addition, we recommend saving projects with password encryption, which offers even more protection against tampering of the project.

  • 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.

  • VDE-2024-024CODESYS: Development System V2.3 affected by two vulnerabilities through corrupted project files2024-05-06csaf · codesys_psirtDE

    Local attackers can cause affected CODESYS Development System V2.3 installations to crash or execute code by opening malicious project files. The CODESYS Development System V2.3 is an IEC 61131-3 programming tool for the industrial controller and automation technology sector. It stores the program code for the controller and its configuration in project files (*.pro).
