At startup, Claude Code executed a command templated in with git config user.email. A maliciously configured user email in git could be used to trigger arbitrary code execution before a user accepted the workspace trust dialog.

Users on standard Claude Code auto-update will have received this fix automatically. Users performing manual updates are advised to update to the latest version.
