GHSA-WHH4-5Q6C-9V3X GitPython: --no-index bypasses diff unsafe-option protections and enables a blind local-file content oracle

Summary GitPython 3.1.59 blocks a previously available local-file read path through unsafe git diff options such as -O/--orderfile. However, the high-level diff API still permits --no-index with the default allowunsafeoptions=False. --no-index changes the semantics of the paths arguments: instead...

Arbitrary Argument Injection

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..., noindex=True into a blind...

CVE-2026-87818

A flaw was found in GitPython. This vulnerability allows an attacker to read arbitrary files on the system by manipulating the --no-index option in the diff API. By combining this with other options, an attacker can repeatedly query local files to extract sensitive information, such as single-lin...
