Summary

Sandbox file operations use check-then-act, bypassing fd-based TOCTOU defenses

Current Maintainer Triage

  • Status: narrow
  • Normalized severity: medium
  • Assessment: Released workspace-only apply_patch remove and mkdir operations were still check-then-act, but the draft overstates scope by bundling broader edit paths; keep it open but narrow it to the actual sandbox-workspace mutation boundary.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Latest published npm version: 2026.3.31
  • Vulnerable version range: <=2026.3.28
  • Patched versions: >= 2026.3.31
  • First stable tag containing the fix: v2026.3.31
