Miggo AIRoot Cause Analysis

The vulnerability relates to unsafe email template manipulation (PRODSECBUG-2275) where unserialize of untrusted data was likely involved. The Filter class handles template processing, and historical Magento vulnerabilities in this component have involved insecure unserialize operations. The advisory's focus on 'underlying model alterations' and CWE-74 (Injection) strongly suggests unsafe deserialization via email template parameters was the vector.
