    Title
    Melhor Envio <= 2.15.11 - Unauthenticated Sensitive Information Exposure via Hardcoded Hash
    Summary
    The Melhor Envio plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.15.11 via the 'run' function, which uses a hardcoded hash. This makes it possible for unauthenticated attackers to extract sensitive data including environment information, plugin tokens, shipping configurations, and limited vendor information.
