Controle de acesso insuficiente ou ausente

A aplicação não valida corretamente quem pode acessar determinado recurso (arquivo, API, função, dados), permitindo que usuários não autorizados façam operações que deveriam estar bloqueadas. É um dos problemas mais comuns em segurança: sem autenticação e autorização robustas, qualquer um consegue fazer o que não deveria.

Ejemplo

Um admin panel acessível via /admin sem login real, ou uma API que retorna dados de qualquer usuário basta mudar um ID na URL sem verificar se você tem permissão. Outro caso: arquivo de configuração com credenciais exposto publicamente porque a aplicação não define permissões de leitura no servidor.

Cómo mitigar

Implemente autenticação forte (sessões, tokens JWT) e autorização em toda operação sensível — verifique explicitamente se o usuário logado tem permissão antes de retornar dados ou executar ações. Use listas de controle de acesso (ACL) ou Role-Based Access Control (RBAC), e nunca confie em IDs de usuário vindos do cliente sem validação server-side.
