Miggo AIRoot Cause Analysis

The vulnerability stemmed from functions generating download URLs using static access tokens stored in file entities (CWE-639). The original getDownloadUrl implementations exposed: 1) sensitive access tokens in URLs (CWE-532), 2) permanent credentials allowing indefinite access, and 3) no proper authorization checks. The patch replaced these with time-limited tokens via openDownload and server-side validation. The functions were directly modified in the security fix commit, indicating their central role in the vulnerability.
