BREW-openclaw-cli-CVE-2026-34426 — OpenClaw: Windows-compatible env override keys could bypass system.run approval binding

Affected: Homebrew: openclaw-cli

## 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.

OpenClaw before 2026.3.22 contains a path traversal vulnerability in Windows media loaders that accepts remote-host file URLs and UNC-style paths before local-path validation. Attackers can exploit this by providing network-hosted file targets that are treated as local content, bypassing intended access restrictions.

WID-SEC-W-2026-0856 — OpenClaw: Mehrere Schwachstellen

Ein Angreifer kann mehrere Schwachstellen in OpenClaw ausnutzen, um beliebigen Code auszuführen, erweiterte Berechtigungen – sogar Administratorrechte – zu erlangen, Daten zu manipulieren, Sicherheitsmaßnahmen zu umgehen, vertrauliche Informationen offenzulegen, einen Denial-of-Service-Zustand herbeizuführen oder andere, nicht näher spezifizierte Angriffe durchzuführen.
