Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

GitPython versions before 3.1.57 are affected. The option denylist used by Repo.archive() omits --add-file and --add-virtual-file, so a caller who can influence archive options can have the library read an arbitrary file on the host, such as one outside the repository, and receive its contents in the returned archive. Upgrade to GitPython 3.1.57, which is listed as the fixed version. The source also describes a related gap in the clone option list (--bundle-uri), which is not covered by this record's package entry.
