Description

OpenClaw versions prior to 2026.2.22 in macOS node-host system.run contain an allowlist bypass vulnerability that allows remote attackers to execute non-allowlisted commands by exploiting improper parsing of command substitution tokens. Attackers can craft shell payloads with command substitution syntax within double-quoted text to bypass security restrictions and execute arbitrary commands on the system.
