    [+] Summary    : A security vulnerability was identified in the Webb Fontaine Trade Portal affecting the codification module (/trade/help/codification). 
                     The issue allows unauthorized users to trigger data export functionality via the /export/excel endpoint without proper validation of session state or user interaction.
                     The backend fails to enforce strict access control and does not verify whether the export request originates from a legitimate user action. 
    				 By initiating a crafted request after triggering a search operation, an attacker may retrieve sensitive codification data in Excel format.
                     Additionally, the application relies on client-side interaction logic while lacking robust server-side verification, resulting in a Broken Access Control / Session Handling flaw.
                     This vulnerability may allow unauthorized data extraction and represents a significant risk in environments handling sensitive trade and customs information.
