Miggo AIRoot Cause Analysis

The vulnerability stems from the 'wiscan.scan' function in index.js where user-supplied 'intf' parameter is unsafely interpolated into an exec() command. The GitHub patch adds a regex check to validate() 'intf' starts with alphanumeric characters, confirming the parameter was previously vulnerable to command injection. The CVE description explicitly references improper input sanitization in this function, and the commit diff shows security-focused validation was added to this exact location.
