File Access Router

This is the routing entry point for filesystem paths, download endpoints, upload pipelines, and file preview handling.

When to Use

  • Parameters, filenames, download endpoints, or import flows influence file paths
  • The target supports upload, preview, transcoding, extraction, sharing, download, or proxied file access
  • You need to decide whether this is path traversal/LFI or an upload-validation/processing-chain issue

Skill Map

  • [Path Traversal LFI](../path-traversal-lfi/SKILL.md): path traversal, file read, wrapper abuse, include chains
  • [Upload Insecure Files](../upload-insecure-files/SKILL.md): upload validation, storage paths, processing chains, overwrite risk, preview/share boundaries

Recommended Flow

1. First identify whether the entry point is a path parameter, download endpoint, or upload workflow 2. Then locate whether the issue appears in accept, store, process, or serve stages 3. Small path-chain and upload-bypass samples are merged into the main topic skills; no separate payload entry is needed
