CVE-2026-43530

OpenClaw: busybox and toybox applet execution weakened exec approval binding

Summary

busybox and toybox applet execution weakened exec approval binding.

Affected Packages / Versions

  • Package: openclaw
  • Ecosystem: npm
  • Affected versions: >= 2026.2.23 < 2026.4.12
  • Patched versions: >= 2026.4.12

Impact

Opaque multi-call binaries such as busybox and toybox could obscure which applet or script-like behavior would actually run, weakening exec approval binding and risk classification.

Technical Details

The fix treats busybox and toybox as opaque mutable script runners and fails closed rather than binding unsafe applet invocations.

Fix

The issue was fixed in #65713. The first stable tag containing the fix is v2026.4.12, and openclaw@2026.4.14 includes the fix.

Fix Commit(s)

  • 666f48d9b882a8a1415ca53f9567c72499d850c9
  • PR: #65713

Release Process Note

Users should upgrade to openclaw 2026.4.12 or newer. The latest npm release, 2026.4.14, already includes the fix.
