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, file read, wrapper abuse, include chains
Upload Insecure Files: upload validation, storage paths, processing chains, overwrite risk, preview/share boundaries

Recommended Flow

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

Install file-access-vuln and it becomes one more candidate the router can pick - when it fits.

A listing is a routing target with a manifest: what it does, which domains it covers, what it costs and who publishes it. Once installed it sits beside your own models and tools, is scored like any other candidate for each request, and shows up in the trace when it wins. Ratings come from workspaces that installed it, one per account.
