OpenClaw versions 2026.1.21 prior to 2026.2.19 contain a command injection vulnerability in the Lobster extension's Windows shell fallback mechanism that allows attackers to inject arbitrary commands through tool-provided arguments. When spawn failures trigger shell fallback with shell: true, attackers can exploit cmd.exe command interpretation to execute malicious commands by controlling workflow arguments.
