CVE-2026-83088

Estado: Pendiente de análisisAlta (7.7)—

Vulnerability in the RDBMS component of Oracle Database Server. Supported versions that are affected are 23.4.0-23.26.3. Easily exploitable 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 unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of RDBMS. CVSS 3.1 Base Score 7.7 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H).
