Summary
OpenClaw's Windows cmd.exe parsing may bypass exec allowlist/approval gating
Details

Summary

On Windows nodes, exec requests were executed via cmd.exe /d /s /c <rawCommand>. In allowlist/approval-gated mode, the allowlist analysis did not model Windows cmd.exe parsing and metacharacter behavior. A crafted command string could cause cmd.exe to interpret additional operations (for example command chaining via &, or expansion via %...% / !...!) beyond what was allowlisted/approved.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Affected: <= 2026.2.1
  • Patched: >= 2026.2.2
  • Latest (npm) as of 2026-02-14: 2026.2.13

Details

  • Default installs: Not affected unless you opt into exec allowlist/approval gating on Windows nodes.
  • Windows execution uses cmd.exe via src/infra/node-shell.ts.
  • The fix hardens Windows allowlist enforcement by:
    • Passing the platform into allowlist analysis and rejecting Windows shell metacharacters.
    • Treating cmd.exe invocation as not allowlist-safe on Windows.
    • Avoiding cmd.exe entirely in allowlist mode by executing the parsed argv directly when possible.
