AnalysisAIv1 – Sep 15, 2026

Improper access controls in Oracle Product Hub, a module of Oracle E-Business Suite 12.2.3 through 12.2.15, let a low-privileged authenticated user reach Internal Operations functionality over HTTP and obtain unauthorized read access to critical product data plus limited insert, update, or delete access to some records. Oracle's own advisory rates this CVSS 7.1 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N), meaning a valid but unprivileged account is enough — no user interaction and no elevated role required. No public exploit code and no CISA KEV listing were identified at time of analysis, but Oracle CPU vulnerabilities in E-Business Suite are historically attractive to attackers because the targets are internet-exposed, data-rich ERP systems.
