Why It Matters

Using inline script blocks prevents the deployment of a strict CSP and increases vulnerability to injection.

How We Check This

We parse the HTML DOM for script tags lacking nonce attributes and elements with on* event handlers.

How to Fix & Implement

Copy-paste configuration blocks tailored for your web server or edge proxy.

Move all inline scripts into external .js files or supply cryptographic nonces

Frequently Asked Questions

Why are inline scripts flagged in security audits?

Because an attacker injecting HTML cannot be distinguished from a legitimate inline script unless cryptographic nonces are enforced.
