Potential fix for https://github.com/community-scripts/ProxmoxVE-Local/security/code-scanning/4
To fix the issue, we need to replace the insecure use of
Math.random()with a cryptographically secure random number generator. Since this code runs in the browser (it's a React component and there's no Node-only syntax), we should use the Web Crypto API'scrypto.getRandomValues. This can be used to generate secure random bytes and convert them to a random string for session ID use. Specifically, we can generate random bytes (or integers), encode them in base36 or hex, and splice that into the session ID in place of the current usage ofMath.random().toString(36).substr(2, 9). We should add a helper function within this file to handle secure random string generation, and update line 423 to use it. No new imports are necessary, as the globalcryptoobject is available in modern browsers.Suggested fixes powered by Copilot Autofix. Review carefully before merging.
