Content-Security-Policy: Protect Your App from XSS Attacks
A Content-Security-Policy (CSP) header tells browsers which sources of content are allowed to load. Without it, your app is vulnerable to cross-site scripting (XSS) attacks.
Why This Matters
XSS attacks can steal user sessions, redirect users to malicious sites, or inject unwanted content. CSP is a critical defense layer.
How to Fix
Add a Content-Security-Policy header to your server responses. Start with a permissive policy and tighten it gradually.
