Description
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.
