Description

OpenClaw has a gateway exec allowlist allow-always bypass via unregistered /usr/bin/script wrapper

Summary

Allow-always persistence did not unwrap /usr/bin/script and similar wrappers to the actual executed target before storing trust decisions.

Impact

A user approval for one wrapped command could persist trust for a wrapper binary that later executed a different underlying program.

Affected Component

src/infra/dispatch-wrapper-resolution.ts, src/infra/exec-wrapper-resolution.ts

Fixed Versions

  • Affected: <= 2026.3.24
  • Patched: >= 2026.3.28
  • Latest stable 2026.3.28 contains the fix.

Fix

Fixed by commit 83da3cfe31 (infra: unwrap script wrapper approval targets).

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. A user must be tricked into taking some action. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.

CVSS metrics in full

The score comes from this vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H

  • Attack vector: Local — a local account, shell or session on the host is needed.
  • Attack complexity: Low — the attack works reliably, with no preparation.
  • Privileges required: Low — an ordinary user account is enough.
  • User interaction: Required — someone has to click, open or visit something.
  • Scope: Unchanged — the damage stays inside the vulnerable component.
  • Confidentiality impact: High — total loss, or loss the attacker controls.
  • Integrity impact: High — total loss, or loss the attacker controls.
  • Availability impact: High — total loss, or loss the attacker controls.
