File Access Vuln

This is a routing skill that helps you figure out whether a file-related vulnerability is path traversal or upload validation. When you're testing download endpoints, upload flows, file previews, or archive extraction, it pushes you toward one of two deeper skills: path-traversal-lfi for read-side issues like LFI and wrapper abuse, or upload-insecure-files for validation bypasses and processing chain attacks. The core value is forcing you to categorize early instead of thrashing between techniques. It's lightweight by design, no payloads here, just triage logic to get you into the right workflow faster.
