Description

Summary

In allowlist mode, system.run guardrails could be bypassed through env -S, causing policy-analysis/runtime-execution mismatch for shell wrapper payloads.

Severity Rationale (Medium)

This issue is rated medium because it is a guardrail/policy bypass in OpenClaw's trusted-operator model, not an authentication boundary break.

  • Authenticated Gateway callers are trusted operators by design.
  • exec approvals/allowlists are operator safety controls.
  • The bug still weakens expected safety behavior and can enable unintended command execution when untrusted content influences tool input.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Vulnerable versions: <= 2026.2.22-2
  • Patched versions: >= 2026.2.23

Latest published npm version checked during triage: 2026.2.22-2.

Technical Impact

When /usr/bin/env is allowlisted, env -S 'sh -c ...' could be treated as allowed non-wrapper argv while runtime still executes shell-wrapper semantics.

Fix Commit(s)

  • a1c4bf07c6baad3ef87a0e710fe9aef127b1f606 (core allowlist/runtime parity hardening)
  • 3f923e831364d83d0f23499ee49961de334cf58b (explicit env -S regressions)

Release Process Note

patched_versions is pre-set to >= 2026.2.23, so this advisory is now public.

OpenClaw thanks @tdjackey for reporting.
