Claude Code vulnerable to arbitrary code execution caused by maliciously configured git email
High8.7CVE-2025-59041 · Published Sep 9, 2025
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.
