Summary

OpenClaw: HGRCPATH, CARGO_BUILD_RUSTC_WRAPPER, RUSTC_WRAPPER, and MAKEFLAGS missing from exec env denylist — RCE via build tool env injection (GHSA-cm8v-2vh9-cxf3 class)

Details

Impact

HGRCPATH, CARGO_BUILD_RUSTC_WRAPPER, RUSTC_WRAPPER, and MAKEFLAGS missing from exec env denylist — RCE via build tool env injection (GHSA-cm8v-2vh9-cxf3 class).

Missing denylist entries allowed hostile build-tool environment variables to influence host exec commands.

OpenClaw is a user-controlled local assistant. This advisory is scoped to the OpenClaw trust model and does not assume a multi-tenant service boundary.

Affected Packages / Versions

Package: openclaw (npm)
Affected versions: < 2026.4.8
Patched versions: 2026.4.8

Fix
