2026.3.22- Upgrade openclaw to this version or later
Description
Summary
Host exec env override sanitization did not fail closed for several package-manager and related redirect variables that can steer dependency fetches or startup behavior.
Impact
An approved exec request could silently redirect package resolution or runtime bootstrap to attacker-controlled infrastructure and execute trojanized content.
Affected Component
src/infra/host-env-security-policy.json, src/infra/host-env-security.ts
Fixed Versions
- Affected:
< 2026.3.22 - Patched:
>= 2026.3.22
Fix
Fixed by commit 7abfff756d (Exec: harden host env override handling across gateway and node).
Affected versions
npm
| Package | Vulnerable | Fixed in |
|---|---|---|
| openclaw | < 2026.3.22 |
2026.3.22 |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.
openclaw npm → 2026.3.22
- npm
npm install openclaw@2026.3.22- yarn
yarn add openclaw@2026.3.22- pnpm

Weakness
CWE-183: Permissive List of Allowed Inputs
The product implements a protection mechanism that relies on a list of inputs (or properties of inputs) that are explicitly allowed by policy because the inputs are assumed to be safe, but the list is too permissive - that is, it allows an input that is unsafe, leading to resultant weaknesses.
