Gestão inadequada de privilégios

A aplicação não controla corretamente quais permissões um usuário ou processo possui, permitindo que ele acesse, modifique ou execute ações além do que deveria. Isso acontece quando a lógica de verificação de privilégios é fraca, ausente ou implementada de forma inconsistente, criando brechas onde um ator com poucos direitos consegue agir como se tivesse privilégios administrativos.

Ejemplo

Um sistema web onde o controle de acesso verifica se o usuário é admin apenas na tela inicial, mas não valida novamente ao processar requisições diretas de API. Um usuário comum consegue chamar endpoints administrativos diretamente, contornando a verificação.

Cómo mitigar

Implemente verificação de privilégios em **toda** operação sensível, não apenas na apresentação — valide no backend antes de executar qualquer ação. Use um modelo de controle de acesso consistente (RBAC ou ABAC), aplique o princípio do privilégio mínimo e revise regularmente quem tem acesso ao quê.
