Your page has inline scripts that could be a security risk. A strong Content Security Policy (CSP) can prevent Cross-Site Scripting (XSS) attacks by controlling which scripts are allowed to run. By using a 'nonce' (a random, one-time-use code) for each script, you can ensure that only the scripts you've authorized are executed by the browser.
An inline script without any security attributes.
<script>alert('This could be malicious');</script>1. Your server should generate a unique, random `nonce` for each page request. 2. Include this nonce in your Content Security Policy HTTP header. 3. Add the same nonce to each of your inline script tags.
<!-- HTTP Header: Content-Security-Policy: script-src 'nonce-r4nd0m...' -->
<!-- In your HTML -->
<script nonce="r4nd0m...">alert('This script is now trusted');</script>A CSP with a nonce acts as a whitelist. The browser will only execute scripts that have the correct nonce, blocking any unauthorized scripts that an attacker might try to inject. This is a powerful defense against XSS attacks.
