Overview

About vulnerability

GitPython versions before 3.1.59 contain an incomplete denylist in the unsafe_git_revision_options guard that omits –contents and -S options, allowing attackers to read arbitrary files by passing these options to Repo.blame(). Attackers can supply revision values like –contents=/etc/passwd to leak file contents through the blame result returned to the caller.
