Miggo AIRoot Cause Analysis

The vulnerability manifests in listinfo CGI handling where user-controlled listname parameters are reflected in error messages without proper validation. The primary vulnerable function is the listinfo CGI script that processes URL parameters and generates 'No such list' errors. Secondary consideration given to formatting functions that might handle the reflected text, though direct patch evidence is limited. The analysis combines CVE descriptions, bug report context about long list name handling, and Mailman's architecture patterns for web request processing.
