CVE-2026-46975

Vulnerability in the RDBMS component of Oracle Database Server. Supported versions that are affected are 19.3-19.31, 21.3-21.22 and 23.4.0-23.26.2. Easily exploitable vulnerability allows unauthenticated attacker with network access via Oracle Net to compromise RDBMS. While the vulnerability is in RDBMS, 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 RDBMS accessible data. CVSS 3.1 Base Score 5.8 (Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:N).

Summary		(es) Vulnerabilidad en el componente RDBMS del servidor de base de datos Oracle. Las versiones compatibles que están afectadas son 19.3-19.31, 21.3-21.22 y 23.4.0-23.26.2. La vulnerabilidad fácilmente explotable permite a un atacante no autenticado con acceso de red a través de Oracle Net comprometer RDBMS. Aunque la vulnerabilidad está en RDBMS, los ataques pueden tener un impacto significativo en productos adicionales (cambio de alcance). Los ataques exitosos de esta vulnerabilidad pueden resultar en acceso no autorizado de actualización, inserción o eliminación a algunos de los datos accesibles de RDBMS. Puntuación Base CVSS 3.1 de 5.8 (Impactos en la integridad). Vector CVSS: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:N).
