Controle de acesso inadequado a recursos

A aplicação falha em validar ou impõe regras insuficientes para determinar quem pode acessar um recurso (arquivo, API, dados, funcionalidade). Um usuário não autorizado consegue contornar essas restrições e acessar o que não deveria, seja por falta de autenticação, autorização fraca ou lógica de controle de acesso bugada.

Example

Um sistema de gestão de RH permite que qualquer funcionário logado acesse `/api/salarios/{id}` substituindo o ID na URL. Sem verificar se o usuário é gestor ou RH, a API retorna dados salariais de qualquer pessoa da empresa. Um dev junior consegue ver quanto ganha o CTO.

How to mitigate

Implemente verificação explícita de permissões antes de qualquer acesso: confirme autenticação (quem é), autorização (o que pode fazer) e aplique o princípio do menor privilégio. Use listas de controle de acesso (ACL), roles bem definidos e sempre valide no backend, nunca confie em dados do cliente.
