Tratamento inadequado de permissões ou privilégios insuficientes

Ocorre quando uma aplicação não valida ou não rejeita adequadamente requisições de usuários que carecem de permissões necessárias para executar uma ação. Em vez de negar o acesso, o sistema permite a operação, expõe informações sensíveis ou executa funções críticas sem verificar direitos. O risco é perda de confidencialidade, integridade ou disponibilidade dos dados.

Example

Uma API REST que deleta registros de usuários verifica apenas se o token JWT é válido, mas não confirma se o usuário autenticado tem permissão 'admin' para deletar. Qualquer usuário logado consegue remover dados de outros usuários ou do sistema.

How to mitigate

Implemente verificações de autorização granulares em cada endpoint ou função sensível, validando não apenas autenticação, mas o nível de privilégio necessário. Use o padrão de controle de acesso baseado em papéis (RBAC) ou atributos (ABAC) e teste permissões antes de executar operações críticas.
