CVE-2026-47046

Vulnerability in the RDBMS component of Oracle Database Server. Supported versions that are affected are 23.4.0-23.26.2. Easily exploitable vulnerability allows unauthenticated attacker with network access via Oracle Net to compromise RDBMS. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of RDBMS as well as unauthorized update, insert or delete access to some of RDBMS accessible data. CVSS 3.1 Base Score 8.2 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H).

Summary		(es) Vulnerabilidad en el componente RDBMS de Oracle Database Server. Versiones compatibles que están afectadas son 23.4.0-23.26.2. Vulnerabilidad fácilmente explotable permite a un atacante no autenticado con acceso a la red a través de Oracle Net comprometer RDBMS. Ataques exitosos de esta vulnerabilidad pueden resultar en la capacidad no autorizada de causar un bloqueo o un fallo repetible con frecuencia (DoS completo) de RDBMS, así como acceso no autorizado de actualización, inserción o eliminación a algunos de los datos accesibles de RDBMS. Puntuación base CVSS 3.1 8.2 (Impactos en la integridad y disponibilidad). Vector CVSS: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H).
