CVE-2026-87818
GitPython 3.1.59 Local File Content Oracle via --no-index
CVSS Score
6.5
EPSS Score
0.0%
EPSS Percentile
0th
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.
