Summary
OpenClaw: Windows-compatible env override keys could bypass system.run approval binding
Details
Summary
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.
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.
Affected Packages / Versions
- Package:
openclaw(npm) - Affected versions:
<= 2026.4.1 - Patched versions:
>= 2026.4.2 - Latest published npm version:

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.
