Duplicate Advisory: GitPython: command injection via unguarded Git options in Repo.archive(), git.ls_remote(), and arbitrary file overwrite via Repo.iter_commits() / Repo.blame()

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.
