Summary

## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-956x-8gvw-wg5v. This link is maintained to preserve external references. ## Original Description GitPython before 3.1.51 fails to guard against dangerous Git options passed as keyword arguments in Repo.archive() and git.ls_remote(), allowing command injection via options such as --exec/--upload-pack (leading to arbitrary command execution). Additionally, Repo.iter_commits() and Repo.blame() do not check for leading-dash revision arguments, so a revision like --output= can cause Git to open and truncate an arbitrary file. Exploitation requires an application that passes attacker-controlled arguments to these methods.

Affected packages

Remediation: No patched version is listed by GitHub.
