AI-suggested
A patch is available to address this vulnerability by expanding the unsafe_git_revision_options denylist to include --contents and -S options. Users should upgrade to a fixed version of GitPython that includes this patch. Until patched, avoid passing untrusted input to Repo.blame() or Repo.blame_incremental() revision parameters. The vendor advisory confirms a fix is available.
Description
GitPython's Repo.blame() and Repo.blame_incremental() methods have an incomplete denylist for unsafe git revision options, omitting the --contents and -S options. This omission allows an attacker to cause arbitrary local file reads by passing these options, which echo file contents into the blame result. The vulnerability affects GitPython versions up to 3.1.58. A patch is available to address this issue by expanding the denylist to include these options.
