Summary
Path traversal in GitPython (CVE-2026-73620). Data can be tampered with by attackers.
Original description
The description as published by the source.
GitPython before 3.1.57 fails to guard git option forwarding in IndexFile.checkout() and TagReference.create(), allowing attackers to pass unsafe options via kwargs. Attackers can use --prefix to overwrite arbitrary files with repository content or -F to read arbitrary files returned in-band.
