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

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
