CVE-2026-61211
Summary
by MITRE • 07/22/2026
Vulnerability in the RDBMS component of Oracle Database Server. Supported versions that are affected are 19.3-19.31 and 23.4.0-23.26.2. Easily exploitable vulnerability allows low privileged attacker having Execute DBMS_CLOUD 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 9.9 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H).

This vulnerability resides within Oracle Database Server's RDBMS component and affects specific version ranges including 19.3 through 19.31 and 23.4.0 through 23.26.2, representing a critical security flaw that can be exploited by low-privileged attackers possessing the DBMS_CLOUD execute privilege. The vulnerability operates through Oracle Net network protocols, allowing attackers with minimal privileges to potentially compromise the entire database management system. This represents a significant escalation risk as the attack vector leverages network connectivity through the standard Oracle database communication channels.
The technical flaw manifests as an easily exploitable weakness that permits unauthorized access to database resources through the DBMS_CLOUD privilege, which typically provides cloud-related functionality but becomes a pathway for more severe attacks when combined with network access. The vulnerability's classification as CVSS 3.1 Base Score 9.9 demonstrates its high severity level with complete impacts across confidentiality, integrity, and availability domains. Attackers can leverage this flaw to achieve complete system compromise, making it particularly dangerous for database environments where sensitive information is stored.
The operational impact extends beyond the immediate RDBMS component, creating a scope change that affects additional Oracle products within the ecosystem. This cascading effect means that successful exploitation could potentially compromise other database-related systems and applications that depend on or interface with the vulnerable Oracle Database Server instances. Organizations may face widespread data breaches, system outages, and potential regulatory compliance violations due to the comprehensive nature of the vulnerability's impact.
Security professionals should implement immediate mitigations including restricting network access to Oracle Database servers, reviewing and limiting DBMS_CLOUD privileges to only essential users, and applying Oracle's security patches as soon as they become available. The vulnerability aligns with CWE-284 (Improper Access Control) and represents a significant concern for organizations operating Oracle Database environments. Mitigation strategies should also include network segmentation, monitoring for unusual database activity, and implementing least privilege access controls to minimize potential attack surfaces. Organizations must prioritize this vulnerability as it provides attackers with a straightforward path to achieve system takeover with minimal required privileges and network connectivity.
