GitPython: Unsafe git option guard bypass via split_single_char_options=False short-option token smuggling enables command execution

SummaryThe checkunsafeoptions guard can be bypassed on every guarded method clone/clonefrom, fetch/pull/push, lsremote, itercommits, blame, archive by combining a single-character kwarg with splitsinglecharoptions=False. The guard's candidate list omits the smuggled option, but transformkwarg emi...

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

SummaryGitPython already know that --upload-pack / --exec are command-exec vectors, they are denylist ingit/remote.py:535 and check by Git.checkunsafeoptions git/cmd.py:963, the thing is thischeck him he is only call from fetch, pull, push and clonefrom, everything else who build a gitargv from...

Semaphore U: OS Command Injection

Summary An OS command injection in repository giturl handling lets any user holding the Manager or Owner role on any project the normal project-collaborator roles achieve remote code execution on the Semaphore server host. Using git's --upload-pack= option, an attacker runs arbitrary commands. Th...
