OpenClaw versions prior to 2026.2.19 contain a command injection vulnerability in the Lobster extension tool execution that uses Windows shell fallback with shell: true after spawn failures. Attackers can inject shell metacharacters in command arguments to execute arbitrary commands when subprocess launch fails with EINVAL or ENOENT errors.
