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.
