OpenClaw: Incomplete host-env-security-policy allows untrusted model to substitute compiler binaries via env overrides

Summary

Incomplete host-env-security-policy.json allows untrusted model to substitute compiler binaries (CC, CXX, CARGO_BUILD_RUSTC, CMAKE_C_COMPILER) via env overrides on approved host exec requests

Current Maintainer Triage

• Status: narrow
• Normalized severity: medium
• Assessment: Shipped v2026.3.28 host-env policy missed compiler override vars, but exploitation still requires an approved host-exec request inside the existing exec trust domain, so medium not high.

Affected Packages / Versions

• Package: openclaw (npm)
• Latest published npm version: 2026.3.31
• Vulnerable version range: <=2026.3.28
• Patched versions: >= 2026.3.31
• First stable tag containing the fix: v2026.3.31
