Summary
OpenClaw exec allowlist safeBins short-option bypass could permit arbitrary file write
Details

Summary

OpenClaw exec allowlist/safeBins policy could be bypassed with attached short-option payloads (for example sort -o/tmp/poc), enabling file-write operations while still satisfying safeBins checks.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Affected versions: <= 2026.2.17
  • Latest published vulnerable version: 2026.2.17
  • Patched in: 2026.2.19

Impact

When tools.exec.security=allowlist and tools.exec.safeBins included affected binaries, attached short-option payloads could bypass safeBins argument validation and permit file-write behavior that should have been denied.
