      "value": "Vulnerability in the Helidon product of Oracle Fusion Middleware (component: Imperative Web Server).  Supported versions that are affected are 4.0.0-4.4.1. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Helidon.  Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Helidon, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in  unauthorized update, insert or delete access to some of Helidon accessible data as well as  unauthorized read access to a subset of Helidon accessible data. CVSS 3.1 Base Score 6.1 (Confidentiality and Integrity impacts).  CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N)."

Vulnerabilidad fácilmente explotable permite a un atacante no autenticado con acceso de red vía HTTP comprometer Helidon. Ataques exitosos requieren interacción humana de una persona distinta al atacante y aunque la vulnerabilidad está en Helidon, los ataques pueden impactar significativamente productos adicionales (cambio de alcance). Ataques exitosos de esta vulnerabilidad pueden resultar en acceso no autorizado de actualización, inserción o eliminación a algunos de los datos accesibles de Helidon, así como acceso de lectura no autorizado a un subconjunto de los datos accesibles de Helidon.
