GHSA-3rp5-jjmw-4wv2: gitpython (CVE-2026-69097)

Package	Ecosystem	Affected	Fixed in
gitpython	PyPI	<3.1.53	3.1.53

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

GitPython versions before 3.1.53 are vulnerable to config section-name injection: section names are written into a git config header with only CR, LF and NUL filtered, so a name containing a closing bracket can inject an arbitrary config directive such as core.sshCommand. An attacker who can supply a submodule name, either through a cloned repository's .gitmodules file or through an application that lets users name submodules, can achieve remote code execution on the next git operation. Upgrade to GitPython 3.1.53 or later; the source gives no other workaround.
