CVE-2026-34312

Vulnerability in the RDBMS component of Oracle Database Server. Supported versions that are affected are 19.3-19.30. Easily exploitable vulnerability allows high privileged attacker having Row Access Method privilege with network access via multiple protocols to compromise RDBMS. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized read access to a subset of RDBMS accessible data. CVSS 3.1 Base Score 2.4 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:L/I:N/A:N).

Summary		(es) Vulnerabilidad en el componente RDBMS del Servidor de Base de Datos Oracle. Las versiones compatibles que están afectadas son 19.3-19.30. Una vulnerabilidad fácilmente explotable permite a un atacante con altos privilegios que tiene el privilegio Row Access Method con acceso a la red a través de múltiples protocolos comprometer el RDBMS. Los ataques exitosos requieren interacción humana de una persona que no sea el atacante. Los ataques exitosos de esta vulnerabilidad pueden resultar en acceso de lectura no autorizado a un subconjunto de datos accesibles del RDBMS. Puntuación base CVSS 3.1 de 2.4 (Impactos en la confidencialidad). Vector CVSS: (CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:L/I:N/A:N).
