Summary
On Windows volumes with 8.3 short names, `actix_files::Files` can serve hidden files through their short-name aliases. The default path check rejects segments that start with a dot, but an alias such as `ENV~1` or `GIT~1` passes this check.
A remote client can read files such as `.env` or `.git/config` in the served directory even when `use_hidden_files()` is not enabled. This can expose secrets or source code.
Upgrade to actix-files 0.7.4 or later. As a workaround, remove sensitive files and directories from the served directory.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
