Summary
## 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: `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.
