Upgrade GitPython to version 3.1.59 or higher.
Overview
GitPython is a python library used to interact with Git repositories
Affected versions of this package are vulnerable to External Control of File Name or Path through the Submodule._config_parser() path in git/objects/submodule/base.py. An attacker can disclose the first line of a readable local file by supplying a malicious .gitmodules file with an [include] directive and triggering normal submodule enumeration, such as repo.submodules. The parser used for .gitmodules inherits include merging, so it follows attacker-controlled include paths during read-only processing. If the included target is not valid git-config, parsing fails with an exception that can expose the file’s contents through the error message, breaking tools that inspect untrusted repositories.
Workarounds
- Disable or avoid processing untrusted repositories’ submodule metadata with GitPython operations such as
repo.submodules/Submodule.iter_items()/Submodule.config()until the library is upgraded, so attacker-controlled.gitmodulesfiles cannot trigger include parsing against local files.
