PYSEC-2026-3983
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.
