CVE-2026-62519: 
Oracle E-Business Suite vulnerability analysis and mitigation

CVE-2026-62519 is an authorization bypass vulnerability in the Oracle Succession Planning product of Oracle E-Business Suite (component: Succession plan), affecting versions 12.2.3 through 12.2.15. The vulnerability was published on July 21, 2026, and is addressed in Oracle's July 2026 Critical Patch Update. It carries a CVSS v3.1 base score of 6.3 (Medium), reflecting low-privilege network exploitation with partial confidentiality, integrity, and availability impacts (Oracle CPU Jul 2026, GitHub Advisory).

The vulnerability is classified under CWE-20 (Improper Input Validation), CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor), CWE-284 (Improper Access Control), and CWE-732 (Incorrect Permission Assignment for Critical Resource), indicating a failure to properly enforce access controls within the Succession plan component. An attacker with low-level network credentials can send crafted HTTP requests to the affected component, bypassing authorization checks to read, modify, or delete data they should not have access to. No user interaction is required, and the attack complexity is low, making exploitation straightforward for any authenticated user (GitHub Advisory, Oracle CPU Jul 2026).

Successful exploitation allows a low-privileged attacker to perform unauthorized read access to a subset of Oracle Succession Planning data, unauthorized update, insert, or delete operations on accessible data, and cause a partial denial of service within the Succession Planning module. The scope is unchanged, meaning the impact is confined to the Succession Planning component itself without direct lateral movement to other systems. However, exposure of HR succession data could have significant organizational consequences, including disclosure of sensitive workforce planning information (Oracle CPU Jul 2026, GitHub Advisory).

There is no public proof-of-concept exploit available, and no evidence of in-the-wild exploitation has been reported as of the time of disclosure (GitHub Advisory). The EPSS score is approximately 0.27%, placing it in the 16th percentile for exploitation likelihood within 30 days. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. The NVD SSVC assessment classifies the exploitation status as "none" and technical impact as "partial," and notes the vulnerability is not automatable (GitHub Advisory).

Oracle has released patches for this vulnerability as part of the July 2026 Critical Patch Update, which addresses affected Oracle E-Business Suite versions 12.2.3 through 12.2.15. Oracle strongly recommends applying the CPU patches immediately, as no long-term workaround is available. As a temporary measure, organizations can restrict network access to the Oracle E-Business Suite Succession Planning component to authorized users only and implement network segmentation to limit exposure. Access logs should be monitored for suspicious activity from low-privileged accounts (Oracle CPU Jul 2026).
