Is it safe to run this on a production API?

Fuzzing involves sending malformed data which can cause unexpected crashes or data states; it is best practice to run these tests in a staging or development environment.

Can this skill detect SQL injection and XSS?

Yes, the skill generates specialized payloads specifically designed to trigger and identify SQL injection, Cross-Site Scripting (XSS), and command injection vulnerabilities.

What types of parameters can be fuzzed?

The skill can fuzz various inputs including URL query parameters, request body data, and HTTP headers to ensure comprehensive coverage.

How do I trigger the fuzz testing?

You can initiate a scan by using the /fuzz-api command and specifying the API endpoint or parameters you want Claude to analyze.

Does it provide a report of the findings?

Yes, Claude will analyze the API's responses and provide a summary of any identified vulnerabilities, errors, or input validation failures.

セキュリティとテスト

Performs automated fuzz testing on REST APIs to identify security vulnerabilities, crashes, and input validation failures using malformed payloads.

The API Security Fuzzer skill empowers Claude to conduct proactive security audits and robustness testing on REST APIs. By automatically generating a diverse range of test inputs—including SQL injection payloads, cross-site scripting (XSS) strings, and boundary values—it probes API endpoints for weaknesses that traditional testing might miss. This skill is essential for developers and security engineers who need to ensure their backend services are resilient against malicious attacks and unexpected data inputs, providing detailed analysis of API responses to pinpoint specific vulnerabilities and ensure proper input validation.
