Summary

Goose CLI 1.35.0 before 1.53.0 contains a local code execution vulnerability that allows attackers to run commands by setting diff.external in a repository's .git/config. Attackers can ship a crafted repository that, when the victim runs goose review, executes git diff without --no-ext-diff, running commands as the user and exposing credentials and provider API keys.
