CVE-2026-101381 in REST Data Services
Summary
by MITRE • 10/21/2026
Vulnerability in Oracle REST Data Services (component: ADP). Supported versions that are affected are 24.2.0-26.1.0. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle REST Data Services. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle REST Data Services accessible data as well as unauthorized read access to a subset of Oracle REST Data Services accessible data. CVSS 3.1 Base Score 5.4 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N).

The identified vulnerability resides within the Application Development Platform component of Oracle REST Data Services, specifically affecting versions ranging from 24.2.0 through 26.1.0. This security flaw represents a significant risk to organizations relying on this platform for exposing database objects and application logic via standard HTTP interfaces. The core technical issue stems from insufficient access control mechanisms within the ADP module, which fails to properly enforce authorization checks before processing certain requests. Consequently, an attacker who has already gained low-privileged network access can manipulate these controls to bypass intended security boundaries. This type of flaw is classically categorized under CWE-269 Improper Privilege Management or CWE-862 Missing Authorization, indicating a failure in the system's ability to restrict actions based on user roles and permissions.
The operational impact of this vulnerability is substantial due to its ease of exploitation and broad attack vector. Because the flaw allows for remote execution over HTTP without requiring any user interaction, it falls squarely into the Remote Code Execution or Unauthorized Access categories as defined by MITRE ATT&CK techniques such as T1078 Valid Accounts if combined with credential theft, or more directly T1528 Steal Application Access Token if tokens are involved in the authentication process. The CVSS 3.1 base score of 5.4 reflects a medium severity level driven primarily by confidentiality and integrity impacts rather than availability. Specifically, successful exploitation enables an attacker to perform unauthorized read operations on sensitive data stored within the Oracle database accessible through REST endpoints. Furthermore, the vulnerability permits unauthorized modifications including updates, inserts, or deletes against specific datasets managed by the service. This dual impact means that not only can proprietary information be exfiltrated, but also critical business records can be corrupted or destroyed, leading to potential regulatory compliance failures and operational disruption.
Mitigation strategies must focus on immediate remediation through patching as well as architectural hardening of the deployment environment. Oracle has released updates for versions 24.2.0-26.1.0 that address these access control deficiencies; organizations should prioritize applying the latest security patches to all affected instances immediately. In addition to software updates, it is crucial to review and tighten network segmentation policies. Since the vulnerability exploits HTTP-based access, ensuring that Oracle REST Data Services are not directly exposed to untrusted networks via firewalls or reverse proxies with strict IP whitelisting can significantly reduce the attack surface. Implementing robust authentication mechanisms such as OAuth 2.0 or JWT validation at the gateway level adds an additional layer of verification before requests reach the application logic. Regular auditing of access logs and implementing intrusion detection systems that monitor for anomalous read/write patterns against database endpoints will also aid in early detection and response to potential exploitation attempts.
