What problem does it solve? When testing web applications for file-related vulnerabilities, it is often unclear whether an issue is a path traversal/LFI problem or an upload validation and processing-chain flaw. This Skill acts as a category router that directs testing to the correct specialized workflow. ## Core Features & Use Cases - Entry Point Classification: Identifies whether the attack surface is a path parameter, download endpoint, or upload workflow. - Skill Routing: Directs testing to the Path Traversal LFI skill (path traversal, file read, wrapper abuse, include chains) or the Upload Insecure Files skill (validation, storage paths, processing chains, overwrite risk, preview/share boundaries). - Stage Localization: Helps locate whether the issue appears in the accept, store, process, or serve stage of file handling. - Use Case: During a CTF or authorized penetration test, you find a download endpoint that takes a filename parameter. Use this Skill to decide whether to pursue path traversal payloads or investigate the upload and preview pipeline instead. ## Quick Start Analyze this download endpoint and tell me whether to test it for path traversal or upload validation issues.
