Description
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).

AI Analysis

Impact

The flaw exists in the RDBMS component of Oracle Database Server, enabling an unauthenticated attacker with network access via Oracle Net to modify database contents. Unauthorized updates, inserts, or deletions of RDBMS data can occur, directly threatening the integrity of stored information. This weakness is a privilege escalation and authorization bypass (CWE‑284). The description indicates that the impact may extend to additional products beyond the database if the attacker succeeds in changing the scope of the vulnerability.

Affected Systems

Oracle Corporation Oracle Database Server versions 19.3 through 19.31, 21.3 through 21.22, and 23.4.0 through 23.26.2 are affected by this vulnerability.

Risk and Exploitability

The CVSS 3.1 Base Score of 5.8 denotes a medium severity focused on integrity. The EPSS score of less than 1% indicates a very low likelihood of widespread automated exploitation. The vulnerability is not listed in CISA’s KEV catalog. Attackers need only network‑level access to the Oracle Net interface, no authentication, and can exploit the flaw from any remote location that can reach the database server.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Apply the latest Oracle Database Server patch released in the July 2026 security alert to eliminate the unauthenticated access flaw.
  • Restrict Oracle Net traffic by implementing firewall rules or network controls to limit unauthenticated connections to the database ports.
  • Enforce the principle of least privilege and configure fine‑grained database access controls to reduce the potential impact of any unauthorized data modification attempts.
