NewCVE-2026-87818 (opens in a new tab)How to fix?
Upgrade GitPython to version 3.1.60 or higher.
Overview
GitPython is a python library used to interact with Git repositories
Affected versions of this package are vulnerable to Arbitrary Argument Injection through the high-level diff API in git/diff.py and git/repo/base.py. An attacker can turn repo.index.diff(..., no_index=True) into a blind local-file content oracle by supplying --no-index together with attacker-chosen paths and an -I/--ignore-matching-lines pattern. This lets the child git process treat the supplied operands as arbitrary filesystem paths, exposing local file content through distinguishable success-or-error responses and allowing repeated queries to recover secrets readable by the process running GitPython.
