Machine-written summary

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

GitPython before 3.1.51 allows command execution through clone, fetch, pull, and push calls. The blocklist added for CVE-2026-42215 can be bypassed with abbreviated option names such as upload_p, so an application that passes attacker-controlled keyword argument names to these calls is exposed. Upgrade to GitPython 3.1.51.
