CVE-2026-101540 in Capacity
Summary
by MITRE • 10/21/2026
Vulnerability in the Oracle Capacity 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 Capacity. While the vulnerability is in Oracle Capacity, 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 Capacity 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).

The identified vulnerability resides within the Internal Operations component of Oracle Capacity, a module integrated into the broader Oracle E-Business Suite ecosystem. This security flaw affects multiple supported versions of the software, specifically ranging from version 12.2.3 through to version 12.2.15. The nature of this defect allows for exploitation by an attacker who possesses only low-level privileges and has network access via the HTTP protocol. Unlike many vulnerabilities that require high-privileged accounts or complex user interaction, this flaw can be triggered remotely with minimal authentication requirements, significantly lowering the barrier to entry for potential adversaries seeking to compromise the system.
The technical mechanism of this vulnerability centers on an improper restriction of data access within the Internal Operations module. When a low privileged attacker sends specifically crafted HTTP requests, they are able to bypass intended authorization checks that should restrict their view and interaction with sensitive information. This failure in access control logic permits the retrieval of data fields or records that were not meant to be visible to users at such privilege levels. The flaw essentially allows an unauthorized entity to traverse security boundaries that are designed to isolate different tiers of user permissions, leading directly to a breach of confidentiality within the application layer.
A critical aspect of this vulnerability is its potential for scope change and lateral impact. Although the technical defect is located specifically in Oracle Capacity, successful exploitation can lead to significant impacts on additional products within the Oracle E-Business Suite environment. This occurs because data integrity and access controls are often shared or interconnected across modules in enterprise resource planning systems. Consequently, compromising one module like Capacity may expose underlying database structures or linked business processes that support other critical applications, thereby amplifying the blast radius of a single point of failure beyond its immediate functional boundary.
The operational impact of this vulnerability is severe, primarily characterized by unauthorized access to critical data and potentially complete access to all Oracle Capacity accessible data. The CVSS 3.1 base score of 7.7 reflects high confidentiality impacts with no direct impact on integrity or availability in the standard assessment model. This means that while an attacker may not immediately disrupt service or alter records, they can exfiltrate sensitive business information such as financial forecasts, resource allocation plans, and operational metrics. The exposure of this data could lead to competitive disadvantage, regulatory non-compliance due to privacy violations, and erosion of stakeholder trust if the breach becomes public knowledge.
From a classification perspective, this vulnerability aligns with CWE-269, which denotes Improper Privilege Management, specifically regarding insufficient authorization checks for critical functions. Furthermore, in terms of adversary tactics as defined by MITRE ATT&CK, this flaw facilitates techniques associated with Initial Access and Credential Access, particularly where low privileged accounts are leveraged to gather intelligence or move laterally within a networked environment. The vector CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N highlights that the attack is Network-based, requires Low Attack Complexity, needs Low Privileges, involves No User Interaction, and exhibits Scope Change with High Confidentiality impact.
To mitigate this risk, organizations running affected versions of Oracle E-Business Suite must apply the latest security patches provided by Oracle for their specific version range from 12.2.3 to 12.2.15. It is imperative that system administrators verify which modules are active in their deployment and ensure that all related components receive the corrective updates addressing this internal operations flaw. Additionally, implementing network segmentation can help limit exposure by restricting HTTP access to these services only from trusted management networks or specific application tiers rather than exposing them broadly across the enterprise perimeter.
Beyond patching, a defense-in-depth strategy should be employed to reduce the likelihood of successful exploitation even if vulnerabilities remain unpatched for short periods. This includes enforcing strict least-privilege principles for all user accounts interacting with Oracle Capacity and monitoring HTTP traffic for anomalous patterns indicative of automated scanning or data exfiltration attempts. Regular audits of access control lists and permission assignments within the application can also help identify misconfigurations that might exacerbate this vulnerability. Continuous monitoring using intrusion detection systems tuned to detect unauthorized data retrieval activities is recommended to provide early warning indicators of potential compromise attempts targeting these specific internal operations endpoints.
