Affected: gitpython-developers GitPython

GitPython before 3.1.57 contains an incomplete denylist in the unsafe_git_archive_options guard that omits --add-file and --add-virtual-file options. Attackers can supply these options to Repo.archive() to read arbitrary files from the filesystem and include them in the returned archive.

Affected: PyPI: GitPython

**Target:** gitpython-developers/GitPython **Tested:** HEAD `07e80555` (2026-07-25), latest release 3.1.55, `git version 2.50.1`

## Summary

`Repo.archive()` does call the option guard, so this is not a missing-guard report. The guard is present and working; the **denylist it consults is incomplete**.

```python # git/repo/base.py:169 unsafe_git_archive_options = [ # Allows arbitrary command execution through the remote git-upload-archive command. "--exec", # Writes output to a caller-controlled filesystem path. "--output", "-o", ] ```

The comment on `--output` states the protected class in the project's own words: an option that lets the caller name **a filesystem path** is unsafe. `--output` is blocked because it *writes* to a caller-chosen path.

`git archive` also accepts `--add-file=<path>` and `--add-virtual-file=<path:content>` (both present in current git; verified against `git version 2.50.1`). `--add-file` *reads* a caller-chosen path — including an absolute path outside the repository — and places the bytes into the archive the caller receives. Neither option is in the list, and no other layer references them:

``` $ grep -rniE "add.file|add_file" git/ git/index/base.py:771: R"""Add files from the working tree, ... # unrelated docstring ```

Net effect: the guard blocks arbitrary file **write** at this sink while permitting arbitrary file **read** at the same sink.

## Reachability proof (verified at the sink)
