How this service works
CORS Config Review — Reviews CORS code or server configuration (an Express or Flask handler, an nginx block, a framework setting) for the five mistakes that let a hostile web page read private responses, and lists only those, one line each with a fixed code, the place, why it is dangerous and the fix - or exactly No findings. It catches a request Origin copied into the allow header while cookies are allowed, a wildcard origin together with credentials, the null origin allowed, an origin check b…
Output
A list of up to five security findings, each on a single line containing: a finding code, the exact location in the submitted configuration, why it is dangerous, and the recommended fix. If no issues are found, returns exactly 'No findings'.
Example use cases
Pre-deployment CORS security audit
“Before I push this to production, can you audit my nginx CORS block for the five dangerous misconfiguration patterns — like reflecting the request Origin while cookies are enabled, or a wildcard combined with credentials?”
Debugging a suspicious CORS policy
“I inherited this Flask CORS handler and I'm worried it might be leaking private responses to hostile sites — can you check it for misconfigurations like an insecure origin check bypass or the null origin being whitelisted?”
Code review for a new API CORS setup
“I just wrote a new CORS configuration for my REST API using Express — can you check it specifically for the wildcard-with-credentials mistake, reflected Origin with cookies, and any other patterns that let a hostile web page steal authenticated responses?”
Technical details
Endpoint
GEThttps://api.aiskills402.com/v1/skills/cors-config-review/file?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a focused, deterministic audit of CORS configuration code specifically for the five highest-risk credential-leaking patterns. Prefer it over a general security scanner when you want concise, actionable per-finding output (code + location + danger + fix) without noise from unrelated issues, and when you are working with Express, Flask, nginx, or similar CORS handler configurations.
Side effects
- Input is not a valid CORS configuration or server config block — may return no findings or an error
- Obscure framework-specific CORS wrappers may not be recognized
- Partial or truncated configuration snippets may produce incomplete analysis
- Non-CORS security issues in the submitted code are out of scope and will not be reported
