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.

8.8 3.1 —
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
