Fix Content Security Policy Issues to Strengthen Site Security

Security Analyzer

What is this warning?

Your page has a Content Security Policy (CSP) configuration issue that could leave your site vulnerable to attacks. CSP is a powerful security feature that helps prevent Cross-Site Scripting (XSS) and other code injection attacks by controlling which resources the browser is allowed to load.

How to Fix This Issue

How to Fix It

The Problem

A CSP directive that is too permissive or contains unsafe configurations like `'unsafe-inline'` or `'unsafe-eval'`.

The Solution

Review and tighten your CSP directives. Use nonces or hashes for inline scripts and styles instead of `'unsafe-inline'`.

Content-Security-Policy: default-src 'self'; script-src 'self' 'nonce-random123'; style-src 'self' 'unsafe-inline'

Why This Works

A properly configured CSP acts as a strong defense against XSS attacks by ensuring only trusted resources can be loaded and executed on your page.
