Summary
OpenClaw's incomplete host env sanitization blocklist allows supply-chain redirection via package-manager env overrides
Details

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).

Severity
9.6 (Critical)
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H
8.5 (High)
CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
