Because environment variables are written to gateway.cmd using unquoted set KEY=VALUE assignments, attackers can inject shell metacharacters such as &, |, ^, %, or ! into environment variable values to break out of the assignment context.

No EPSS data is available, and the vulnerability is not listed in the CISA KEV catalog. The likely attack vector is inferred: an attacker must provide a value for an environment variable that influences the script generation; this could be achieved remotely via an interface that accepts custom environment variables or locally by setting environment variables before invoking the vulnerable code. Because the injection occurs during script generation, successful exploitation requires access that can cause the script to be generated and run. Given the moderate CVSS score and absence of observable exploit in the public domain, immediate remediation is recommended to prevent potential code execution."}}}}, "created": "2026-03-19T08:55:04.538003+00:00", "updated": "2026-03-25T11:51:37.713641+00:00", "vendors": ["openclaw", "openclaw$PRODUCT$openclaw"]}
