Falta de validação de condições excepcionais

A fraqueza ocorre quando o software não valida ou valida incorretamente situações anômalas que raramente acontecem durante a operação normal. O desenvolvedor assume que certas condições 'nunca vão acontecer', deixando o código vulnerável quando elas de fato ocorrem — seja por entrada malformada, estado corrompido ou cenários edge case não previstos.

Exemplo

Um parser JSON que só testa o caminho feliz: carrega e processa um JSON válido, mas quando recebe um arquivo com caracteres especiais, tamanho excepcional ou estrutura quebrada, falha silenciosamente ou causa comportamento indefinido em vez de rejeitar explicitamente o entrada inválida.

Como mitigar

Sempre validar entradas e estados, não presumir cenários 'impossíveis': use try-catch, verificações de limites, e testes que explorem casos anormais (fuzzing, boundary testing). Falhe de forma segura e explícita — nunca em silêncio.
