Summary
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. A flaw was found in GitPython.
This vulnerability requires that the application using GitPython forwards user-influenced input to the blame function's revision parameter. Red Hat severity: Moderate — CVSS 6.5 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N).
