Description

Summary

A Windows system.run approval-integrity mismatch in the cmd.exe /c path could allow trailing arguments to execute while approval/audit text reflected only a benign command string.

This requires an authenticated operator context using the approvals flow and a trusted Windows node.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Latest published vulnerable version (as of 2026-02-21): 2026.2.19-2
  • Vulnerable range: <=2026.2.19-2
  • Patched version (planned next release): 2026.2.21

Attack Scenario

  1. An authenticated operator approval is created for a benign command text (for example, echo).
  2. A system.run request uses cmd.exe /c with extra trailing arguments.
  3. Prior behavior could bind approval/audit text to the benign command while still executing the full argument tail on the node.

Impact

  • Local command execution on the trusted Windows node process account.
  • Approval/audit command text integrity mismatch.

Fix

  • Canonicalize the full command tail after cmd.exe /c.
  • Reuse one shared command canonicalization/validation path for validation, approval matching, and execution/audit text.
  • Add regression coverage for trailing-argument smuggling and approval binding.
