CVE-2026-41373 — OpenClaw < 2026.3.31 - Compiler Binary Substitution via Environment Variable Override in Host Execution Policy

Affected: OpenClaw

OpenClaw before 2026.3.31 contains an incomplete host-env-security-policy.json that fails to restrict compiler binary environment variables, allowing untrusted models to substitute CC, CXX, CARGO_BUILD_RUSTC, and CMAKE_C_COMPILER via environment overrides. Attackers with approved host-exec requests can override compiler binaries to execute arbitrary code during build processes.

GHSA-g8xp-qx39-9jq9 — OpenClaw: Incomplete host-env-security-policy allows untrusted model to substitute compiler binaries via env overrides

Affected: npm: openclaw

## 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`

## Fix Commit(s) - `e277a37f896b5011a1df06e6490c6630074d0afa` — 2026-03-30T20:06:32+01:00
