Content-Security-Policy allows 'unsafe-inline' / 'unsafe-eval'

Part of Security, which counts for 30% of the overall score. When this check fires it deducts 8 points from that category, once per scan, no matter how many places it turns up.

What it detects

A CSP directive permits 'unsafe-inline' or 'unsafe-eval', which re-enables the inline-script and eval execution that CSP exists to block.

Why it matters

A Content-Security-Policy that includes 'unsafe-inline' or 'unsafe-eval' turns off the protections CSP is there to provide. With unsafe-inline, injected inline scripts and event handlers run; with unsafe-eval, string-to-code paths like eval keep working. An XSS bug that CSP would have blocked becomes exploitable again.

How to fix it

Remove 'unsafe-inline' and 'unsafe-eval' from script-src and style-src. Move inline scripts to external files, and where inline is unavoidable use per-response nonces or hashes instead of the blanket keyword. Refactor any eval/new Function usage so unsafe-eval is not needed. Roll the policy out in report-only mode first to find what breaks.
