Summary

In openclaw@2026.3.1, node system.run approval-path hardening rewrote wrapper command argv in a way that changed execution semantics. A command shown/approved as a shell payload (for example echo SAFE) could execute a different local script when wrapper argv were rewritten.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Affected: 2026.3.1 (latest published npm version as of March 2, 2026)
  • Fixed release: 2026.3.2 (released)

Technical Details

Root cause was in node-host approval hardening for system.run:
  • src/node-host/invoke-system-run-plan.ts rewrote argv[0] to the resolved executable.
  • Wrapper resolution unwrapped dispatch wrappers, so input like ['env','sh','-c','echo SAFE'] resolved executable sh.
  • The approved plan could become ['/bin/sh','sh','-c','echo SAFE'] while approval text remained echo SAFE.
That rewrite changed runtime behavior: /bin/sh interprets the extra sh positional argument as a script path, enabling execution of a local ./sh file from approved cwd instead of the approved payload text.

Impact

Approval-integrity break in host=node execution flow: operator-visible command text and executed behavior could diverge.
Exploit preconditions:
  • attacker can influence wrapper argv and place a local file in approved working directory,
  • operator grants approval for the displayed command.
