Vulnerability in the Oracle Installed Base product of Oracle E-Business Suite (component: Create Item Instance). Supported versions that are affected are 12.2.3-12.2.15. 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 access to critical data or complete access to all Oracle Installed Base accessible data as well as unauthorized update, insert or delete access to some of Oracle Installed Base accessible data. CVSS 3.1 Base Score 7.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N).
AnalysisAI
Unauthorized data access in Oracle Installed Base (a module of Oracle E-Business Suite, versions 12.2.3 through 12.2.15) lets a low-privileged, network-based attacker read all data accessible to the Installed Base application and modify some of it via HTTP. Oracle rates it CVSS 7.1, driven by high confidentiality impact and partial integrity impact with no availability effect. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, though it is disclosed as part of the Oracle July 2026 Critical Patch Update.
Technical ContextAI
Oracle Installed Base is an asset-lifecycle-tracking application within the Oracle E-Business Suite (EBS) applications tier, which runs on Oracle Application Server / Oracle HTTP Server and is accessed over HTTP by authenticated business users. The flaw is in the 'Create Item Instance' component. No CWE was assigned in the source data, but the described behavior - a low-privileged user gaining access to data beyond their authorization scope and being able to insert/update/delete some records - is consistent with a broken access control / improper authorization weakness (CWE-285-class), notwithstanding the input's 'Authentication Bypass' tag, which is not fully consistent with the CVSS PR:L (privileges required) metric. The affected component is server-side EBS application code shared across the 12.2.x release line; no CPE strings were provided in the intelligence, so exact platform enumeration relies on Oracle's own version list.
RemediationAI
Apply the Oracle July 2026 Critical Patch Update, which contains the fix for this issue; consult https://www.oracle.com/security-alerts/cpujul2026.html and apply the specific patch listed there for Oracle E-Business Suite 12.2 (Patch available per vendor advisory - Oracle does not publish a separate point-release version number, so cite the CPU patch level rather than an invented version). No exact standalone fix version was provided in the input, so identify the correct patch by cross-referencing your EBS 12.2.x patchset in the CPU advisory. Until patched, reduce exposure by restricting network access to the Oracle Installed Base / EBS application endpoints - for example placing the EBS applications tier behind VPN or IP allow-listing and removing any direct internet exposure of the Installed Base responsibilities - and review and tighten EBS responsibility/menu assignments so low-privileged accounts cannot reach the 'Create Item Instance' function; the trade-off is that URL-firewalling and responsibility hardening can block legitimate remote users and integrations, so test against business workflows before enforcing. Monitor EBS access logs for anomalous Installed Base data access by low-privilege accounts as a detective control.
