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.
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
Impact
An approved exec request could silently redirect package resolution or runtime bootstrap to attacker-controlled infrastructure and execute trojanized content.
CVE-2026-41387 has a CVSS score of 9.6 (High). The vector is network-reachable, no privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (2026.3.22); upgrading removes the vulnerable code path.

Security releases
Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.
Remediation advice
Fixed by commit 7abfff756d (Exec: harden host env override handling across gateway and node).
Frequently Asked Questions
- What is CVE-2026-41387? CVE-2026-41387 is a high-severity security vulnerability in openclaw (npm), affecting versions < 2026.3.22. It is fixed in 2026.3.22.
- How severe is CVE-2026-41387? CVE-2026-41387 has a CVSS score of 9.6 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of openclaw are affected by CVE-2026-41387? openclaw (npm) versions < 2026.3.22 is affected.
- Is there a fix for CVE-2026-41387? Yes. CVE-2026-41387 is fixed in 2026.3.22. Upgrade to this version or later.
- Is CVE-2026-41387 exploitable, and should I be worried? Whether CVE-2026-41387 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2026-41387 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
