Miggo AIRoot Cause Analysis

The vulnerability stems from unsafe handling of carrier gateway configurations in shipment settings. Magento's AbstractCarrier class and shipment controllers are central to processing carrier-related requests. The high-confidence _doShipmentRequest() function is a core method for carrier communication that would execute requests to external URLs. The medium-confidence Save controller handles admin input for shipments, which could pass unvalidated parameters to vulnerable carrier functions. Both locations align with the described attack vector involving admin-privileged users manipulating shipment settings to trigger SSRF.
