CVE-2026-62519 in Succession planning
Summary
by MITRE • 07/22/2026
Vulnerability in the Oracle Succession planning product of Oracle E-Business Suite (component: Succession plan). 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 Succession planning. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Succession planning accessible data as well as unauthorized read access to a subset of Oracle Succession planning accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Succession planning. CVSS 3.1 Base Score 6.3 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L).

Analysis

This vulnerability resides within Oracle E-Business Suite's Succession Planning component, specifically affecting versions 12.2.3 through 12.2.15. The flaw represents a significant security weakness that enables low-privileged attackers to exploit network-based HTTP access points to compromise the succession planning functionality. The vulnerability's classification as easily exploitable indicates that attackers require minimal technical expertise or resources to leverage this weakness effectively, making it particularly dangerous in production environments where such systems handle sensitive organizational data.
The technical nature of this vulnerability stems from insufficient authorization controls within the Succession Planning module, allowing authenticated users with minimal privileges to perform unauthorized operations against the system's data. Attackers can exploit this flaw to execute unauthorized update, insert, or delete operations on specific subsets of succession planning data, while simultaneously gaining read access to confidential information that should remain restricted. The partial denial of service component suggests that successful exploitation could disrupt normal operational workflows within the succession planning system, potentially affecting critical HR processes and organizational planning activities.
From a security impact perspective, this vulnerability affects all three core principles of information security as defined by the CIA triad. The confidentiality impact is rated as low, indicating unauthorized access to sensitive succession planning data that may include employee career progression information, talent development plans, and organizational hierarchy details. The integrity impact is similarly rated as low, reflecting the potential for unauthorized modifications to succession planning records that could misrepresent organizational talent strategies. The availability impact also carries a low rating but indicates the system's partial operational capacity may be compromised during exploitation attempts.
The CVSS 3.1 base score of 6.3 places this vulnerability in the medium severity category, with the attack vector classified as network-based (AV:N) requiring no user interaction (UI:N) and minimal access complexity (AC:L). The low privilege requirement (PR:L) means that attackers do not need elevated system permissions to exploit this weakness, while the unscoped impact (S:U) indicates that the vulnerability affects the target system without requiring additional system compromise. This vulnerability aligns with CWE-284 (Improper Access Control) and potentially CWE-310 (Cryptographic Issues) depending on implementation details, representing a classic example of insufficient authorization controls in enterprise applications.
Organizations should prioritize immediate remediation through Oracle's security patches and updates for affected versions, implementing network segmentation to limit access to succession planning modules, and establishing enhanced monitoring for unauthorized access attempts. Additional mitigations include enforcing stricter authentication mechanisms, implementing role-based access controls with principle of least privilege, and conducting regular vulnerability assessments of the E-Business Suite environment. The ATT&CK framework categorizes this vulnerability under privilege escalation techniques, specifically targeting the credential access and defense evasion tactics that attackers might employ to maintain persistent access to succession planning data. Regular security awareness training for HR personnel who interact with succession planning systems is also recommended to prevent social engineering attacks that might complement network-based exploitation attempts.
The operational impact extends beyond immediate data compromise, potentially disrupting critical talent management processes and violating compliance requirements for sensitive employee data handling. Organizations should conduct thorough risk assessments to determine the full scope of potential data exposure and implement comprehensive incident response procedures to address successful exploitation attempts. System administrators must verify the effectiveness of implemented patches through vulnerability scanning and penetration testing activities to ensure complete remediation of this security weakness across their Oracle E-Business Suite deployments.
