Summary
OpenClaw: Windows-compatible env override keys could bypass system.run approval binding
Before OpenClaw 2026.4.2, system-run approval binding normalized environment override keys differently from host execution. Windows-compatible keys could be omitted from the approval binding while still being injected at execution time.
Affected Packages / Versions
- Package:
openclaw(npm) - Affected versions:
<= 2026.4.1 - Patched versions:
>= 2026.4.2 - Latest published npm version:
2026.4.1
Fix Commit(s)
7eb094a00d80e9f6bf0e62f2c45d3b88ff67c04d, align approval binding with execution-time env-key normalization
Release Process Note
The fix is present on main and is staged for OpenClaw 2026.4.2. Publish this advisory after the 2026.4.2 npm release is live.
Thanks @iskindar for reporting, and thanks @wsparks-vc for coordination.
Impact
An approved command could run with attacker-chosen environment overrides that were not represented in the approval binding. This created an approval-integrity gap for affected host-exec flows.

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.

Frequently Asked Questions
- What is GHSA-98CH-45WP-CH47? GHSA-98CH-45WP-CH47 is a medium-severity security vulnerability in openclaw (npm), affecting versions <= 2026.4.1. It is fixed in 2026.4.2.
- Which versions of openclaw are affected by GHSA-98CH-45WP-CH47? openclaw (npm) versions <= 2026.4.1 is affected.
- Is there a fix for GHSA-98CH-45WP-CH47? Yes. GHSA-98CH-45WP-CH47 is fixed in 2026.4.2. Upgrade to this version or later.
- Is GHSA-98CH-45WP-CH47 exploitable, and should I be worried? Whether GHSA-98CH-45WP-CH47 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 GHSA-98CH-45WP-CH47 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.
