Description

OpenClaw versions prior to 2026.2.22 contain an allowlist bypass vulnerability in system.run exec analysis that fails to unwrap env and shell-dispatch wrapper chains. Attackers can route execution through wrapper binaries like env bash to smuggle payloads that satisfy allowlist entries while executing non-allowlisted commands.
