## MiddlewareDAO.php Exposes SQL Injection Risk in Permission Check Logic
A security analysis of the MiddlewareDAO.php file has identified potential SQL injection vulnerabilities within the permission verification system. The class, responsible for validating user access based on cargo and resource mappings, processes user-supplied inputs that could be exploited if sanitization protocols are incomplete or inconsistent across different code paths.

The flagged code segment involves the variables $idPessoa and $recurso, which are incorporated into SQL queries. While the analysis notes that prepared statements with bound parameters are present in some sections—such as the query targeting the 'permissao' table—concerns remain about whether all input flows are uniformly protected. The evaluation, generated via the OLLAMA AI provider, emphasizes that direct use of user-supplied data in database operations creates an attack surface that could allow unauthorized data access or manipulation if any query path lacks proper parameterization.

The implications extend beyond this single file. Middleware components handling authentication and authorization are high-value targets; a successful injection could bypass access controls, expose sensitive permission structures, or enable privilege escalation within the affected system. Organizations deploying this code should conduct a comprehensive audit of all database interactions involving the MiddlewareDAO class, verify that prepared statements are consistently applied, and ensure input validation occurs before any data reaches the persistence layer. The analysis underscores that partial protection is insufficient—security must be enforced across every query execution path.
