CVE-2026-62559 in HRMS
Summary
by MITRE • 07/22/2026
Vulnerability in the Oracle HRMS (US) 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 HRMS (US). While the vulnerability is in Oracle HRMS (US), 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 HRMS (US) accessible data. CVSS 3.1 Base Score 6.8 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:N).

This vulnerability resides within Oracle HRMS (US) component of the Oracle E-Business Suite, specifically targeting the Internal Operations functionality. The affected versions span from 12.2.3 through 12.2.15, representing a substantial release range that indicates this flaw has persisted across multiple updates. The vulnerability classification as easily exploitable suggests that sophisticated attack techniques are not required, making it particularly dangerous for organizations running these specific Oracle E-Business Suite versions. The attack vector requires only network access via HTTP, meaning that malicious actors can potentially exploit this weakness from remote locations without requiring physical presence or complex initial access methods.
The security implications of this vulnerability are severe given its high privileged attacker requirement combined with the potential for critical data compromise. The CVSS 3.1 base score of 6.8 reflects the significant confidentiality impact, with a vector indicating network accessibility (AV:N), low attack complexity (AC:L), high privilege requirements (PR:H), and no user interaction needed (UI:N). The scope change aspect is particularly concerning as it suggests that successful exploitation could potentially affect additional Oracle products beyond the directly targeted HRMS (US) component. This expanded impact area represents a significant risk to organizations with integrated Oracle ecosystems where interconnected applications share common data repositories or authentication mechanisms.
The technical flaw within Internal Operations appears to permit unauthorized access to critical Oracle HRMS (US) data, potentially enabling attackers to gain complete access to all data accessible through this specific module. This level of access could include sensitive employee information, payroll records, compensation data, and other confidential human resources information that organizations consider highly sensitive. The attack scenario involves a sophisticated threat actor who has already established network connectivity to the target environment and possesses elevated privileges within the Oracle system. Such actors can leverage this vulnerability to extract sensitive data without detection, potentially leading to identity theft, financial fraud, or corporate espionage.
Organizations should prioritize immediate remediation efforts by applying the relevant Oracle patches and updates that address this specific vulnerability. The implementation of network segmentation and access controls can provide additional layers of protection while patches are deployed. Monitoring for unusual network activity patterns and conducting regular security assessments can help detect potential exploitation attempts. Security teams should also review access controls within their Oracle environments to ensure that privilege levels are appropriately restricted and that the principle of least privilege is maintained. The vulnerability's classification as a scope change issue emphasizes the importance of comprehensive risk assessment across all interconnected Oracle applications to prevent cascading impacts from a single exploited weakness.
This vulnerability aligns with CWE-284 (Improper Access Control) and may relate to ATT&CK techniques involving privilege escalation and credential access. Organizations should also consider implementing database activity monitoring solutions that can detect anomalous data access patterns indicative of potential exploitation attempts. Regular security awareness training for administrators and system operators remains crucial in preventing successful exploitation through social engineering or insider threats that could complement this technical vulnerability. The extended impact potential makes this vulnerability particularly relevant to organizations with complex Oracle E-Business Suite implementations where multiple interconnected modules share common data access points.
