Who should care

Oracle REST Data Services administrators, security teams, and IT personnel responsible for patching and vulnerability management should assess exposure and prioritize remediation. This includes reviewing the current deployment, identifying potential entry points, and ensuring that appropriate security measures are in place. Additionally, operators and platform administrators should be aware of the potential impacts and take necessary actions to mitigate

Why it matters

CVE-2026-101365 is a medium-severity vulnerability in Oracle REST Data Services that requires attention from administrators and security teams to prevent potential unauthorized data access and service disruption. The vulnerability allows high-privileged attackers with network access via HTTP to compromise the service. Oracle REST Data Services instances, especially those exposed to high-privileged network access, should be assessed for exposure and patched or updated as necessary. The impacts of this vulnerability include potential unauthorized data access and modification, partial denial of service, and the need for verification of affected versions and exposure. Remediation priority follows from the medium severity and potential impacts.

• Potential unauthorized data access and modification
• Partial denial of service (partial DOS) of Oracle REST Data Services
• Need for verification of affected versions and exposure
• Priority patching for high-privileged network access scenarios
