Doc Text:
A flaw was found in GitPython. This vulnerability allows an attacker to read arbitrary files from the filesystem. By exploiting an incomplete denylist in the `unsafe_git_archive_options` guard, an attacker can supply specific options, such as `--add-file` or `--add-virtual-file`, to the `Repo.archive()` function. This leads to unauthorized information disclosure at the privileges of the process running GitPython.

Description OSIDB Bzimport 2026-08-13 12:14:20 UTC
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.
