CVE-2026-83490 in iRecruitment
Summary
by MITRE • 09/16/2026
Vulnerability in the Oracle iRecruitment 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 iRecruitment. While the vulnerability is in Oracle iRecruitment, 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 iRecruitment accessible data as well as unauthorized update, insert or delete access to some of Oracle iRecruitment accessible data. CVSS 3.1 Base Score 8.5 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:L/A:N).

The identified vulnerability resides within the Internal Operations component of Oracle iRecruitment, a module integrated into the broader Oracle E-Business Suite ecosystem. This security flaw affects supported software versions ranging from 12.2.3 through 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 HTTP to the affected system. Unlike many vulnerabilities that are confined strictly to their module of origin, this specific flaw presents a significant scope change risk. While the technical entry point is within Oracle iRecruitment, successful exploitation can lead to lateral movement or privilege escalation effects that compromise additional products within the enterprise environment. This cross-product impact amplifies the severity of the issue beyond what might be expected from an isolated module defect, as it potentially exposes interconnected systems and data stores to unauthorized intrusion.
From a technical perspective, the vulnerability enables unauthorized access to critical organizational data and grants complete read access to all information accessible through Oracle iRecruitment. Furthermore, the flaw permits attackers to perform unauthorized update, insert, or delete operations on certain datasets within the application's scope. This combination of confidentiality and integrity breaches indicates that the underlying code likely fails to properly validate user input or enforce proper authorization checks before executing database commands. The ability to modify data introduces risks such as payroll fraud, manipulation of candidate records, or corruption of human resources metrics. These actions can have severe operational consequences for organizations relying on accurate recruitment and employee management processes.
The severity of this vulnerability is quantified by a CVSS 3.1 Base Score of 8.5, which classifies it as High severity. The vector string (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:L/A:N) highlights several critical factors driving this score. The Attack Vector is Network, indicating remote exploitability without physical access. The Attack Complexity is Low, meaning the vulnerability can be exploited with minimal effort or specialized conditions. Privileges Required are listed as Low, confirming that even standard user accounts can trigger the flaw. User Interaction is None, suggesting automated exploitation is possible. Notably, the Scope is Changed to Yes, which elevates the score because an attacker compromising one component affects resources beyond its original security boundary. The Confidentiality impact is High due to full data exposure, while Integrity is Low but still significant given the potential for unauthorized modifications. Availability remains unaffected in this specific vector, focusing the risk primarily on data privacy and integrity rather than service disruption.
In terms of industry standard classifications, this vulnerability aligns with CWE-269 Improper Privilege Management or CWE-862 Missing Authorization, depending on whether the root cause is an elevation of privilege or a failure to check permissions for specific actions. The ability to modify data also touches upon CWE-798 Use of Hard-coded Credentials if authentication bypasses are involved, though the primary issue appears to be authorization logic flaws within the HTTP interface. From a tactical standpoint as described in MITRE ATT&CK, this vulnerability facilitates Initial Access via valid accounts and potentially Data Exfiltration or Impact through data manipulation. The cross-product impact suggests potential lateral movement capabilities, which may relate to techniques involving trusted relationships between systems within an enterprise network.
To mitigate these risks, organizations must apply the latest security patches provided by Oracle for their specific version of E-Business Suite. Immediate remediation is critical given the low barrier to entry and high impact profile. In addition to patching, implementing strict access controls and role-based permissions can limit the damage if a vulnerability is exploited. Network segmentation should be reviewed to ensure that iRecruitment servers are not overly exposed to untrusted networks. Web Application Firewalls may help detect and block exploit attempts by filtering malicious HTTP requests before they reach the application layer. Regular audits of user privileges within Oracle E-Business Suite are recommended to ensure that low-privileged accounts do not possess excessive permissions that could be leveraged in conjunction with this flaw. Continuous monitoring for anomalous data access patterns can also aid in early detection of exploitation attempts.
