goshs is a SimpleHTTPServer written in Go. Prior to version 2.1.0, when `goshs` is launched with WebDAV enabled (`-w`), the mode-restriction flags `--read-only`, `--upload-only`, and `--no-delete` are enforced only on the primary HTTP port. The WebDAV port is wired straight to `golang.org/x/net/webdav.Handler` with no equivalent guard, so an authenticated WebDAV client can `PUT`, `DELETE`, `MKCOL`, `MOVE`, and `COPY` despite the operator's stated intent. Version 2.1.0 patches the issue.

Affected: Go: goshs.de/goshs/v2

# WebDAV listener ignores `--read-only`, `--upload-only`, and `--no-delete` mode flags

**Ecosystem:** Go **Package:** `goshs.de/goshs/v2` (`github.com/patrickhener/goshs`) **Affected:** `<= v2.0.9` (every release that ships the WebDAV handler)

## Summary

When `goshs` is launched with WebDAV enabled (`-w`), the mode-restriction flags `--read-only`, `--upload-only`, and `--no-delete` are enforced only on the primary HTTP port. The WebDAV port is wired straight to `golang.org/x/net/webdav.Handler` with no equivalent guard, so an authenticated WebDAV client can `PUT`, `DELETE`, `MKCOL`, `MOVE`, and `COPY` despite the operator's stated intent.

## Details

[`httpserver/server.go:207-238`](https://github.com/patrickhener/goshs/blob/v2.0.9/httpserver/server.go#L207-L238) — the WebDAV mux registers only `IPWhitelistMiddleware`, `ServerHeaderMiddleware`, and optionally `BasicAuthMiddleware`. There is no `fs.ReadOnly || fs.UploadOnly || fs.NoDelete` check on the WebDAV path. The HTTP mux in the same file (lines 134-204) does check these flags on every state-changing route.
