Bug Fixes

  • Refused batch script CLI spawning on Windows: Blocked spawning .bat/.cmd CLI scripts (including npm's claude.cmd shim) on Windows to prevent command injection via cmd.exe metacharacter re-parsing (BatBadBut / CVE-2024-27980 class). Windows users relying on the npm shim should switch to the native installer, an explicit claude.exe path, or a platform wheel that bundles the CLI (#1127)
  • Windows cmd.exe metacharacter rejection: resume and session_id values containing cmd.exe metacharacters (& | < > ^ % ! ") or newlines now raise ValueError on Windows, preventing injection even if a cmd.exe hop is reintroduced. POSIX behavior is unchanged (#1127)
  • Dash-prefixed extra_args value binding: extra_args now uses --flag=value form when the value starts with -, preventing a dash-leading value from being misinterpreted as a separate CLI flag (#1127)

Internal/Other Changes

  • Updated bundled Claude CLI to version 2.1.216
