CVE-2026-101376 Oracle Corporation CVE debrief

Who should care

Defenders responsible for Oracle REST Data Services instances, particularly those with high privilege access, should assess exposure and apply patches or updates as soon as possible to prevent potential unauthorized data access and partial denial of service.

Why it matters

CVE-2026-101376 is a medium-severity vulnerability in Oracle REST Data Services that requires high privilege access and network accessibility to exploit. Defenders should assess exposure, prioritize patching, and restrict high privilege access to prevent potential data breaches and partial denial of service.

• Defenders need to verify if their Oracle REST Data Services instances are exposed and prioritize patching to prevent potential data breaches.
• High privileged attackers could exploit this vulnerability to gain unauthorized access to sensitive data.
• A partial denial of service could occur if the vulnerability is exploited, impacting service availability.
• Defenders should review and restrict high privilege access to minimize the attack surface.

Technical summary

The vulnerability in Oracle REST Data Services (component: Database Actions) is easily exploitable and allows high privileged attackers with network access via HTTP to compromise the service. Successful attacks can result in unauthorized update, insert or delete access to some of Oracle REST Data Services accessible data, unauthorized read access to a subset of Oracle REST Data Services accessible data, and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle REST Data Services. The CVSS 3.1 Base Score is 4.7 (Confidentiality, Integrity and Availability impacts).

Defensive priority

Medium priority for defenders to assess exposure and apply patches, given the high privilege requirement and network accessibility.

Recommended defensive actions

• Assess exposure of Oracle REST Data Services instances, particularly versions 24.2.0 through 26.1.0.
• Apply patches or updates provided by Oracle Corporation as soon as possible.
• Review network access controls and ensure high privilege access is properly restricted.
• Monitor for potential unauthorized data access and partial denial of service.
• Review compensating controls for exposed systems while remediation is scheduled and verified.
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.
• Track exceptions, retest remediated assets, and close the item only after evidence is documented.

Evidence notes

The CVE record and Oracle advisory provide details on the vulnerability, affected versions, and potential impacts. However, specific exploitation instances or victim information are not provided. Defenders should verify if their Oracle REST Data Services instances are exposed, particularly versions 24.2.0 through 26.1.0, and prioritize patching to prevent potential unauthorized data access and partial denial of service.
