BREW-openclaw-cli-CVE-2026-43530 — OpenClaw: busybox and toybox applet execution weakened exec approval binding

Affected: Homebrew: openclaw-cli

## 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.

OpenClaw versions 2026.2.23 before 2026.4.12 contain a weakened exec approval binding vulnerability in busybox and toybox applet execution that allows attackers to obscure which applet would actually run. Attackers can exploit opaque multi-call binaries to bypass exec approval mechanisms and weaken risk classification of unsafe applet invocations.
