GitPython versions prior to 3.1.51 contain multiple vulnerabilities due to insufficient validation of caller-supplied options in several public APIs. Specifically, `Repo.archive()` and `git.ls_remote()` allow arbitrary command execution by forwarding unsafe Git options without proper checks. Additionally, `Repo.iter_commits()` and `Repo.blame()` permit arbitrary file overwrite by placing unvalidated revision arguments before the end-of-options separator, enabling file truncation. These issues arise because the existing unsafe option checks are only applied to network commands and not extended to these other APIs.
