Controle de acesso inadequado a recursos

A aplicação falha em validar ou aplica incorretamente as restrições de acesso, permitindo que usuários não autorizados acessem dados ou funcionalidades que deveriam estar protegidas. É uma das fragilidades mais comuns em segurança: o código não verifica corretamente quem está pedindo acesso e simplesmente concede.

Exemplo

Um e-commerce que permite acessar o perfil de qualquer cliente substituindo o ID na URL (ex: /usuario/123 → /usuario/124), sem validar se o usuário autenticado é o dono daquele perfil. Um atacante consegue ver dados pessoais, histórico de compras e endereços de outras pessoas.

Como mitigar

Implemente verificações explícitas em cada acesso a recurso: autentique o usuário, identifique qual recurso ele quer acessar, e valide se as permissões dele cobrem aquele recurso específico. Use listas de controle de acesso (ACLs) ou papéis (RBAC/ABAC) consistentemente em toda a API ou aplicação, nunca deixando a segurança implícita.
