Claude Code can execute commands prior to the startup trust dialog

  • Disclosed: 03.10.2025
  • Updated: 11.10.2026 10:22

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.
