CVSS v3.1

6.1

MEDIUM

Description

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.
