How this service works
CSP Header Review — Reviews ONE Content-Security-Policy header, with any note pasted beside it, and lists only the gaps that let injected script run or let the page be framed, one line each with a fixed code, the directive, why it hurts and the fix - or exactly No findings. It catches unsafe-eval or unsafe-inline in the script directive, a star, a data source or a bare scheme as a script source, a policy with neither object-src nor a default-src, a missing base-uri, a missing frame-ancestors, a…
Output
A list of security findings, one per line, each containing a fixed finding code, the affected CSP directive, an explanation of why the configuration is dangerous, and a concrete fix. If no exploitable gaps are detected, the endpoint returns exactly 'No findings'.
Example use cases
Pre-deployment CSP audit
“I'm about to deploy my site — can you review this CSP header and tell me if anything would let an attacker inject and run scripts? Here it is: "default-src 'self'; script-src * 'unsafe-eval'; frame-ancestors 'self'"”
Clickjacking vulnerability check
“My security team flagged that our page might be frameable by attackers. Can you check this Content-Security-Policy header and tell me specifically if frame-ancestors is missing or misconfigured? Header: "default-src 'self' https:; script-src 'self'"”
Post-incident CSP hardening review
“We just had an XSS incident and I want to lock down our CSP. Please audit this header and list every directive gap that could allow script injection, with a fix for each: "script-src 'self' data: 'unsafe-inline'; style-src 'self'"”
Technical details
Endpoint
GEThttps://api.aiskills402.com/v1/skills/csp-header-review/file?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a focused, line-by-line audit of a single Content-Security-Policy header specifically for script injection and framing vulnerabilities, rather than a general web security scanner or full HTTP response header analysis. It is ideal for CI/CD pipelines, pre-deployment checks, or rapid triage after a security incident where you already have the CSP string and need actionable, coded findings fast.
Side effects
- Malformed or missing CSP header value returns an error or empty analysis
- Extremely long or complex policies with many directives may produce truncated output
- Policies using nonce-based or hash-based allowlists may be misclassified if context is incomplete
- Non-CSP header strings passed as input may yield unexpected or meaningless findings
