PYSEC-2026-3840 GitPython: Unguarded git option forwarding in Repo.init enables arbitrary command execution via --template clone hooks

Summary Repo.init forwards kwargs verbatim to git init with no unsafe-option guard and no allowunsafeoptions parameter. git init --template= copies /hooks/ into the new repo's .git/hooks, so an attacker-controlled template kwarg plants a hook that executes on the next git operation → arbitrary co...

GitPython: Unguarded git read-tree option forwarding in IndexFile.from_tree/reset/merge_tree enables arbitrary file overwrite

SummaryIndexFile.fromtree, IndexFile.reset → fromtree and IndexFile.mergetree append caller-influenced treeish strings positionally to git read-tree with no unsafe-option guard, no allowunsafeoptions parameter, and no -- separator. git read-tree --index-output= writes the resulting index to an...
