Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for gitpython-developers/GitPython, gitpython, gitpython.
  2. 2Review the reported fix. Update gitpython-developers/GitPython to 3.1.60; gitpython to 3.1.60; gitpython to 3.1.60; gitpython to 3.1.60 if you use the affected versions. Test the change in a non-production environment first.

Upstream source description

GitPython 3.1.59 fails to restrict the --no-index option in the high-level diff API, allowing attackers to read arbitrary filesystem paths as repository operands. Attackers can combine --no-index with -I/--ignore-matching-lines to create a content-dependent Boolean oracle, repeatedly querying local files to recover single-line secrets through distinguishable success or error responses.
