CVE-2026-101378 · Severity: medium · CVSS 4.3 · Published 2026-10-20

Oracle REST Data Services is a middleware component that exposes Oracle databases as REST APIs for application integration. This vulnerability allows a low-privileged attacker on the network to modify or delete data in the database without proper authorization, potentially compromising data accuracy and business logic. Exploitation requires valid user credentials but no user interaction, making it a straightforward attack for insiders or compromised accounts.

Technical details

The ADP component of Oracle REST Data Services (versions 24.2.0 through 26.1.0) fails to properly enforce access controls on data modification operations, allowing low-privileged authenticated users with network access via HTTP to perform unauthorized insert, update, or delete operations on sensitive data. An attacker with valid credentials can bypass intended integrity checks to manipulate database records. A fix is available in patched versions.

Affected products
