Miggo AIRoot Cause Analysis

The vulnerability stems from missing registry domain validation in Azure authentication providers. The commit diff shows these two functions were modified to add host validation logic (validateHost) in the Provide methods. Prior to the patch, these functions handled token exchange without checking if the target registry was an authorized Azure Container Registry, making them the entry points for the credential leakage vulnerability. The high confidence comes from direct correlation between the vulnerability description, patch commit changes, and CWE-287/497 mappings.
