Miggo AIRoot Cause Analysis

The vulnerability stems from two key points: 1) The password is explicitly added to command-line arguments in Lynx::Command::Basic, as shown in the code snippet from basic.rb. 2) The Run#perform method executes these commands without sanitization. Together, these allow sensitive credentials to appear in process listings. Both functions are directly referenced in advisory code snippets and CVE analysis, confirming their role in the exposure.
