Tratamento inadequado de permissões ou privilégios insuficientes

Ocorre quando o aplicativo não verifica corretamente se o usuário ou processo possui as permissões necessárias antes de executar uma ação sensível. O código assume que a operação foi autorizada sem validar o contexto de segurança, permitindo que usuários sem privilégio acessem recursos ou executem ações restritas.

Exemplo

Um painel administrativo que lista usuários sensíveis sem validar se o requisitante é administrador; qualquer usuário autenticado consegue acessar a rota /admin/users apenas porque a aplicação não verifica role ou permissão específica.

Como mitigar

Implementar controle de acesso explícito: valide permissões em cada operação sensível (authorization checks), use padrões como RBAC ou ABAC, e considere frameworks que forçam validação (ex: @RequireRole, middleware de permissões). Teste negativo: confirme que usuários sem privilégio são bloqueados.
