Fuzzing Apis
This skill allows Claude to conduct automated fuzz testing on REST APIs. It identifies potential security flaws and robustness issues by injecting various malformed inputs, boundary values, and random data.
Install
/plugin marketplace add jeremylongshore/claude-code-plugins-plus-skills
/plugin install api-fuzzer@claude-code-plugins-plusRun these inside Claude Code. The skill comes with its plugin.
What this skill does
This skill enables Claude to perform automated fuzz testing on APIs to discover vulnerabilities, crashes, and unexpected behavior. It leverages malformed inputs, boundary values, and random payloads to generate comprehensive fuzz test suites. Use this skill when you need to identify potential SQL injection, XSS, command injection vulnerabilities, input validation failures, and edge cases in APIs. Trigger this skill by requesting fuzz testing, vulnerability scanning, or security analysis of an API. The skill is invoked using the `/fuzz-api` command.
How it works
- API Interaction: It sends these inputs to the specified API endpoints.
- Result Analysis: It analyzes the API's responses and behavior to identify vulnerabilities, crashes, and unexpected results, such as SQL injection errors or XSS vulnerabilities.
When to use it
- Identify potential security vulnerabilities in an API.
- Test the robustness of an API against unexpected inputs.
- Ensure proper input validation is implemented in an API.
Best practices
- Context: Provide context about the expected behavior of the API.
- Iteration: Run multiple fuzzing sessions with different input sets for thorough testing.
