Falha de verificação de autorização

A aplicação não valida se o usuário tem permissão para acessar um recurso ou executar uma ação específica. O código presume que quem chegou até ali já é confiável, pulando a checagem de privilégios. Qualquer atacante que consiga se autenticar (ou nem isso) pode fazer operações que deveria estar proibido.

Exemplo

Um admin painel que verifica login, mas depois deixa qualquer usuário logado deletar outros perfis acessando /admin/delete-user/123 diretamente. A autenticação existe, a autorização não.

Como mitigar

Implemente verificações de autorização (ACL, RBAC ou atributo-based) antes de cada operação sensível: confirme se o usuário tem a role ou permissão necessária. Não confie em autenticação alone — é login que prova quem você é, autorização que prova o que você pode fazer.
