AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H
Network HTTP access with low complexity, but requires pre-existing high application privileges (PR:H); full module takeover yields C:H/I:H/A:H with unchanged scope.

Lifecycle Timeline
2DescriptionCVE.org
Vulnerability in the Oracle HCM Common Architecture product of Oracle E-Business Suite (component: Internal Operations). Supported versions that are affected are 12.2.3-12.2.15. Easily exploitable vulnerability allows high privileged attacker with network access via HTTP to compromise Oracle HCM Common Architecture. Successful attacks of this vulnerability can result in takeover of Oracle HCM Common Architecture. CVSS 3.1 Base Score 7.2 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H).
AnalysisAI
Full compromise of the Oracle HCM Common Architecture module (Internal Operations component) within Oracle E-Business Suite is possible, allowing an attacker who already holds high-level application privileges to take over the module over the network via HTTP. The flaw affects EBS releases 12.2.3 through 12.2.15 and carries a CVSS 3.1 score of 7.2 with full confidentiality, integrity, and availability impact. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but Oracle rates it 'easily exploitable' for an authenticated actor.
Technical ContextAI
Oracle HCM (Human Capital Management) Common Architecture is a shared framework layer inside Oracle E-Business Suite 12.2, the on-premise ERP/HR application stack that runs on Oracle WebLogic/Application Server fronted by HTTP. The affected 'Internal Operations' component handles back-end HCM processing shared across HR modules. Oracle did not assign a CWE (CWE: N/A) and the advisory does not disclose the root-cause class; the vendor tag 'Information Disclosure' hints at a confidentiality-affecting defect, though the CVSS vector shows full C/I/A impact indicating a broader takeover rather than pure disclosure. Because EBS 12.2 is a monolithic, session-authenticated web application, exploitation is reached through authenticated HTTP requests to the application tier.
RemediationAI
Apply the fixes delivered in the Oracle Critical Patch Update of July 2026 (https://www.oracle.com/security-alerts/cpujul2026.html); this is Patch available per vendor advisory, though the input does not enumerate a specific patched build number, so identify the exact patch for your EBS 12.2.x level from that CPU. Oracle strongly recommends applying CPUs promptly and running only supported EBS versions. As compensating controls until patched, restrict network reach to the EBS application tier so only trusted internal hosts can send HTTP requests to the HCM/Internal Operations endpoints, and tighten authorization so that high-privilege application accounts (the PR:H prerequisite) are minimized, closely audited, and protected with strong/MFA-backed authentication - this reduces the pool of accounts able to trigger the flaw, at the cost of administrative overhead. Review application access logs for anomalous privileged activity against HCM modules.
