OpenClaw versions prior to 2026.2.23 contain an allowlist bypass vulnerability in system.run guardrails that allows authenticated operators to execute unintended commands. When /usr/bin/env is allowlisted, attackers can use env -S to bypass policy analysis and execute shell wrapper payloads at runtime.
