OpenClaw safeBins stdin-only bypass via sort output and recursive grep flags

GHSA-4685-c5cp-vp95 · CVE-2026-31996

Published · Modified

Description

Summary

tools.exec.safeBins could be bypassed for filesystem access when sort output flags (-o / --output) or recursive grep flags were allowed through safe-bin execution paths.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Affected versions: <= 2026.2.17
  • Patched versions: >= 2026.2.19
  • Latest published version at triage time: 2026.2.17

Impact

In deployments that enabled tools.exec.safeBins, an attacker with access to command execution flows could turn intended stdin-only safe-bin usage into file writes (sort -o) or recursive file reads (grep -R).
