Miggo AIRoot Cause Analysis

The vulnerability description indicates insufficient session expiration but provides no specific code references, commit diffs, or patch details. Magento's session management is typically handled through PHP native session mechanisms and custom classes like Magento\Framework\Session\SessionManager, but without concrete evidence from patch comparisons or official documentation identifying specific flawed functions, we cannot confidently pinpoint exact vulnerable functions. The advisory describes the vulnerability at a architectural level rather than identifying specific method implementations.
