An unauthenticated attacker can send a crafted Authorization Basic header containing CR or LF bytes to inject forged log lines, breaking the one-request-per-line structure of access logs and enabling log forgery against downstream log consumers. The built-in combined, common, default, and short formats are affected, as well as any custom format that references :remote-user. Affected versions: morgan 1.2.0 through 1.10.1.

Workarounds: use a custom format string that does not include :remote-user."},{"lang":"es","value":"Impacto: El token :remote-user del middleware de registro morgan extrae el nombre de usuario de autenticación Basic del encabezado de solicitud de autorización y lo escribe en el flujo de registro sin neutralizar los caracteres de control.
