        Some older versions of SVR.JS are vulnerable to cyberattacks. It&apos;s
        recommended to update your SVR.JS version to the newest one. If you find
        a security issue with SVR.JS, report it as soon as possible to
        vulnerability-reports@svrjs.org. We&apos;ll mitigate that vulnerability
        if it is possible.
