Command execution prior to Claude Code startup trust dialog
High8.7CVE-2025-59536 · Published Oct 3, 2025
Due to a bug in the startup trust dialog implementation, Claude Code could be tricked to execute code contained in a project before the user accepted the startup trust dialog. Exploiting this requires a user to start Claude Code in an untrusted directory. 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. Thank you to https://hackerone.com/avivdon for reporting this issue!
