BREW-OPENCLAW-CLI-CVE-20… (GHSA-J7P2-QCWM-94V4)

Vulnerability from osv_homebrew – Published: 2026-08-13 17:21 – Updated: 2026-09-25 08:57 – Source website

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

GHSA-J7P2-QCWM-94V4

Vulnerability from github – Published: 2026-03-31 23:59 – Updated: 2026-05-06 02:36

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
