Although these workarounds will not correct the underlying vulnerability, they can help block known attack vectors. When a workaround reduces functionality, this is\nidentified below as \u201cImpact of workaround\u201d.\n\nTo exploit the vulnerabilities, access the project on file level is required. This can be prevented by the security settings of the Automation Builder projects, accessible via the menu \u201cProject\u201d \u2192 \u201cProject\nSettings\u2026\u201d \u2192 \u201cSecurity\u201d.\n\n\u2022 CVE-2025-3394: In the project settings, set \u201cSecurity\u201d to \u201cIntegrity check\u201d. This prevents anyone\nto access or modify the content of the Automation Builder project file. Projects can be opened\nand used without any limitations.\n\n\u2022 CVE-2025-3395: In the project settings, set \u201cSecurity\u201d to \u201cEncryption\u201d. This prevents unauthorized users to open the project. Authorized users can open the project and with that exploit the\nvulnerability",

Recognize that VPNs may have vulnerabilities and should be updated to the most current version available. Also, understand that VPNs are only as secure as the connected devices.",
