HIGH 7

Published 2026-06-16 · Last modified 2026-06-18

OpenClaw before 2026.4.29 contains a path traversal vulnerability in the install helper that allows workspace .env files to override the npm_execpath configuration used for bundled runtime dependency installation. Attackers with workspace access can execute unintended local package-manager executables during dependency setup to compromise the build environment.
