GHSA-3wxw-xv34-2frg: gitpython (CVE-2026-78679)

Package	Ecosystem	Affected	Fixed in
gitpython	PyPI	<3.1.59	3.1.59

Machine-written summary

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

GitPython versions before 3.1.59 are vulnerable to arbitrary local file read through TagReference.create(), where a caller-supplied positional reference value such as a file option bypasses the unsafe-option guard meant to block --file and -F. An attacker who can influence the reference value passed by an application that uses the default settings can read a file the host process can access, and its contents are returned in the annotated tag message. Upgrade to GitPython 3.1.59, which is the listed fixed version.
