Recommendation: Monitor — no exploitation signal at the moment.

OpenClaw before 2026.5.27 contains an arbitrary code execution vulnerability in skill install flows where workspace .env files can override the Homebrew executable selection. Attackers with access to trusted operator workspaces can execute unintended Homebrew-compatible executables during skill setup to compromise the system.
