GHSA-98ch-45wp-ch47: OpenClaw: Windows-compatible env override keys could bypass system.run approval binding

mediumCVSS 4.0 6.9

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.

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

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.
