Duplicate Advisory: GitPython 3.1.59: --no-index bypasses diff unsafe-option protections and enables a blind local-file content oracle

Published Sep 9, 2026·Updated Sep 30, 2026

NVD Description

## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-whh4-5q6c-9v3x. This link is maintained to preserve external references. ## Original 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.
