CVE-2026-71062

Estado: AnalizadaAlta (8.5)—

Vulnerability in the RDBMS component of Oracle Database Server. Supported versions that are affected are 23.4.0-23.26.3. Difficult to exploit vulnerability allows low privileged attacker having Authenticated User privilege 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 takeover of RDBMS. CVSS 3.1 Base Score 8.5 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H).

CVSS
