Which versions of Oracle Installed Base are affected by EUVD-2026-47508?

Oracle E-Business Suite versions 12.2.4-12.2.15 contain a data integrity vulnerability in the Installed Base module (CVSS 8.1) that allows authenticated, low-privileged users to read, modify, or…

How to fix or mitigate EUVD-2026-47508?

Within 24 hours, identify all users with access to the Installed Base Create Item Instance component and audit their privilege levels; disable unnecessary low-privileged accounts and implement comprehensive HTTP request logging for the affected module. Within 7 days, conduct a data integrity audit of the Installed Base module for unauthorized modifications, deletions, or data access; implement role-based access controls restricting Installed Base functionality to specific authorized users and limiting network access via firewall rules. Within 30 days, monitor Oracle's security advisory channels and CPU schedule for an available patch to Oracle E-Business Suite versions 12.2.4 through 12.2.15; apply the patch immediately to all affected production and non-production instances upon release, and complete thorough testing in a controlled environment before production deployment.

HIGH 8.1

DescriptionCVE.org

Vulnerability in the Oracle Installed Base product of Oracle E-Business Suite (component: Create Item Instance). Supported versions that are affected are 12.2.4-12.2.15. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Installed Base. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Installed Base accessible data as well as unauthorized access to critical data or complete access to all Oracle Installed Base accessible data. CVSS 3.1 Base Score 8.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N).

AnalysisAI

Data compromise in Oracle Installed Base (Create Item Instance component) of Oracle E-Business Suite versions 12.2.4 through 12.2.15 allows a low-privileged attacker with HTTP network access to read, create, modify, or delete all data accessible to the Installed Base module. The flaw carries a CVSS 3.1 base score of 8.1 with high confidentiality and integrity impact but no availability impact, and was disclosed in Oracle's July 2026 Critical Patch Update. There is no public exploit identified at time of analysis, no CISA KEV listing, and no EPSS score provided in the source data.

Technical ContextAI

Oracle Installed Base (CSI) is an Oracle E-Business Suite module that tracks the lifecycle and configuration of deployed product instances (assets, item instances, and their relationships). The affected 'Create Item Instance' component is exposed over HTTP through the EBS web application tier, meaning it is reachable via the standard Oracle Application Framework / servlet front end rather than only through internal APIs. No CWE was assigned by the source, but the combination of network reachability, a low-privilege prerequisite, and full read/write access to module data is consistent with a broken access-control / authorization weakness (CWE-284/CWE-863 class) in which an authenticated user can operate on data beyond their intended authorization scope. The vendor-supplied 'Authentication Bypass' tag points in this direction, though the CVSS vector indicates the attacker still needs some authenticated access (PR:L).

RemediationAI

Apply the fixes delivered in the Oracle July 2026 Critical Patch Update - patch available per vendor advisory at https://www.oracle.com/security-alerts/cpujul2026.html; no discrete fixed version string was published in the source data beyond the CPU bundle, so apply the CPU patch corresponding to your EBS 12.2.x release level. Because Oracle CPU fixes are cumulative, ensure the July 2026 CPU is applied on top of your current 12.2.4-12.2.15 codeline. If immediate patching is not possible, compensating controls include restricting network access to the EBS web tier and the Installed Base / Create Item Instance endpoints to trusted internal users via reverse-proxy or WAF URL filtering (trade-off: may block legitimate remote Installed Base users), tightening EBS responsibility and menu assignments so low-privilege accounts cannot reach Installed Base functions (trade-off: operational review overhead and potential disruption to CSI users), and enabling audit logging on Installed Base data changes to detect unauthorized create/modify/delete activity. Treat any low-privilege EBS account as a potential attack origin and review account provisioning.
