2DescriptionCVE.org
Vulnerability in the Oracle MES for Process Manufacturing 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 low privileged attacker with network access via HTTP to compromise Oracle MES for Process Manufacturing. While the vulnerability is in Oracle MES for Process Manufacturing, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle MES for Process Manufacturing accessible data. CVSS 3.1 Base Score 7.7 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N).
AnalysisAI
Unauthorized data disclosure in Oracle MES for Process Manufacturing (versions 12.2.3-12.2.15) allows a low-privileged attacker with network HTTP access to bypass internal authorization controls and gain complete access to all data accessible by the MES component. The scope change (S:C in CVSS) means successful exploitation can cascade into other Oracle E-Business Suite products, amplifying the confidentiality impact beyond the MES module itself. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid, low-privileged user account in Oracle E-Business Suite with network access to the application tier via HTTP - meaning the attacker must already be authenticated to EBS, but only at the lowest privilege tier. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 7.7 (High) is driven primarily by network accessibility (AV:N), low attack complexity (AC:L), low required privileges (PR:L), no user interaction (UI:N), scope change (S:C), and high confidentiality impact (C:H). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the Oracle Critical Patch Update (CPU) for August 2026, available via Oracle's advisory at https://www.oracle.com/security-alerts/cspuaug2026.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Identify all instances running Oracle MES versions 12.2.3-12.2.15 and document network exposure; assess which systems are internet-facing or accessible to low-privilege users. …
