Description

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 [email protected] includes the fix.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for openclaw, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update openclaw to 2026.4.12 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-2cq5-mf3v-mx44 is resolved across your whole dependency graph.

  3. Workarounds

    Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
