Falha na verificação de autorização

A aplicação não valida ou valida incorretamente se um usuário tem permissão para acessar um recurso ou executar uma ação. O código assume que autenticação (saber quem é) é suficiente, ignorando autorização (saber o que pode fazer), permitindo que usuários acessem dados ou façam operações que não deveriam.

Example

Um usuário comum consegue listar faturas de outro cliente porque a API verifica se ele está logado, mas não valida se aquela fatura pertence a ele. Ou um analista consegue executar uma exclusão em massa porque o botão existe no HTML, mas o backend não checa se ele tem permissão de admin.

How to mitigate

Implemente verificações de autorização em toda operação sensível: antes de retornar dados, valide se o usuário autenticado tem acesso àquele recurso específico (RBAC, ABAC ou ACL). Teste permissões no backend sempre, nunca confie em controles apenas na UI.
