Impact

This vulnerability in Oracle REST Data Services, as described, permits high‑privileged attackers with network access over HTTP to create, delete, or modify data that the service exposes. The vulnerability is an improper access control flaw—based on the description, it is inferred that privileged users can perform operations they should not be able to. This does not allow arbitrary code execution or denial of service; the primary consequence is loss of data integrity, with the potential to alter or delete critical information accessible through the REST endpoints.

Affected Systems

Oracle REST Data Services version 24.2.0 through 26.1.0 of the Core component is affected. Within those releases, the Core service is vulnerable to the described improper access control flaw.

Risk and Exploitability

The CVSS v3.1 score of 4.9 reflects moderate severity, limited to integrity impact. The attack vector is over the network via HTTP, requiring high privileges to authenticate. EPSS is below 1%, and the vulnerability is not listed in the CISA KEV catalog, indicating no known wild exploitation. Nevertheless, an adversary with elevated rights can modify any data that the REST service exposes, making timely remediation essential.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Deploy the latest Oracle REST Data Services release (v26.1.1 or later) or apply the vendor patch for the Core component that addresses the improper access control flaw.
  • Restrict HTTP access to the REST Data Services by applying network segmentation, firewall rules, or VPN requirements, ensuring only authorized, least‑privileged traffic can reach the service.
  • Review and enforce strict role‑based access controls within the service configuration, ensuring that only users with the minimal required permissions can perform create, delete, or modify operations, and monitor logs for attempts to perform unauthorized actions.
