Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
GitPython versions from 3.1.30 before 3.1.47 are affected. The unsafe-option guard blocks options such as upload-pack and receive-pack but not their underscore spellings (upload_pack and receive_pack) passed as Python keyword arguments to clone_from, fetch, pull, or push. If an application passes attacker-controlled keyword arguments into these calls, an attacker can run arbitrary commands as the application's account, even with allow_unsafe_options left at its default. Upgrade to GitPython 3.1.47 or later; no other workaround is listed.
