Miggo AIRoot Cause Analysis

The vulnerability stems from insecure XML parsing in Zend_Feed components. The commit patches show that both Zend_Feed::importString and Zend_Feed_Abstract's constructor were modified to add libxml_disable_entity_loader protections. Prior to the fix, these functions parsed XML (via DOMDocument::loadXML) without disabling external entity resolution, allowing attackers to inject malicious entities. The vulnerable code paths are directly in the XML processing methods before entity loader hardening was implemented.
