Description

OpenClaw versions prior to 2026.2.19 contain a command injection vulnerability in Windows Scheduled Task script generation where environment variables are written to gateway.cmd using unquoted set KEY=VALUE assignments, allowing shell metacharacters to break out of assignment context. Attackers can inject arbitrary commands through environment variable values containing metacharacters like &, |, ^, %, or ! to achieve command execution when the scheduled task script is generated and executed.
