CVE-2026-101398 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. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Capacity accessible data as well as unauthorized update, insert or delete access to some of Oracle Capacity accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Capacity. CVSS 3.1 Base Score 7.6 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:L).

The identified vulnerability resides within the Internal Operations component of Oracle Capacity, a module integrated into Oracle E-Business Suite versions 12.2.3 through 12.2.15. This security flaw is classified as an easily exploitable issue that permits low-privileged attackers to compromise the integrity and availability of the application environment. The attack vector requires network access via HTTP, meaning that any user with valid but minimal credentials on the Oracle E-Business Suite platform can initiate exploitation attempts over standard web protocols without requiring additional authentication layers or complex setup procedures. This accessibility significantly lowers the barrier for entry compared to vulnerabilities requiring high privileges or physical proximity, thereby increasing the likelihood of successful compromise in environments where internal network segmentation is not strictly enforced between application tiers and user endpoints.
From a technical perspective, the flaw allows an attacker with low-level access to manipulate critical data structures within Oracle Capacity. The consequences are multifaceted, impacting confidentiality, integrity, and availability as reflected by the CVSS 3.1 base score of 7.6. Specifically, successful exploitation grants unauthorized read access to sensitive business information stored in the capacity planning modules, which may include resource allocation schedules, workforce data, or financial projections depending on organizational usage patterns. Beyond mere data exfiltration, the vulnerability permits unauthorized modifications such as inserts, updates, and deletions of records within accessible datasets. This capability undermines the reliability of operational metrics and decision-making processes that rely on accurate capacity planning data. Furthermore, the attacker can trigger conditions leading to a partial denial of service, disrupting normal operations for other users by consuming excessive resources or corrupting stateful sessions associated with the affected component.
The impact extends beyond immediate data loss or disruption, as it erodes trust in the integrity of enterprise resource planning systems. In an industry context, this type of vulnerability aligns with CWE-269 Improper Privilege Management and CWE-862 Missing Authorization, indicating that the application failed to adequately verify whether a low-privileged user should have access to specific internal operations functions. The ability to cause partial denial of service also relates to CWE-400 Uncontrolled Resource Consumption or CWE-755 Improper Handling of Exceptional Conditions, suggesting potential flaws in how input validation and resource limits are enforced within the HTTP handling logic of the Internal Operations component. From an adversary behavior standpoint, this vulnerability maps closely to ATT&CK technique T1078 Valid Accounts, as it relies on legitimate but insufficiently restricted credentials, and potentially T1564 Hidden Files and Directories if the attacker attempts to obscure their modifications or persistence mechanisms within the application database.
Mitigation strategies must prioritize immediate patching of Oracle E-Business Suite to the latest available release that addresses this specific vulnerability in the Internal Operations component. Organizations should verify their current version against the supported range and apply security patches provided by Oracle as soon as they are validated for production stability. In addition to software updates, implementing strict network segmentation is critical; access to HTTP endpoints serving Oracle E-Business Suite should be restricted to authorized user subnets or virtual private networks rather than being exposed broadly across corporate LANs where lateral movement could occur after initial compromise. Web Application Firewalls can also provide a layer of defense by inspecting HTTP traffic for patterns indicative of exploitation attempts, such as unusual SQL injection syntax or excessive resource consumption requests targeting the Internal Operations endpoints. Regular auditing of user privileges is essential to ensure that low-privileged accounts do not possess unnecessary access rights to sensitive modules like Oracle Capacity, thereby reducing the attack surface available to potential intruders who have obtained valid credentials through phishing or other social engineering tactics.
