AnalysisAIv1 – Sep 15, 2026

Oracle BI Publisher versions 8.2.0.0.0, 12.2.1.4.0 and 26.01.0.0.0 contain a flaw in the BI Platform Security component that lets a low-privileged attacker with network access to the SOAP interface alter or delete critical report and platform data, and read a limited portion of it. The CVSS 3.1 base score is 8.5 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:H/A:N), driven by a scope change that means compromise of BI Publisher can cascade into other Oracle Analytics components. No public exploit code or active exploitation has been identified at time of analysis, and no CWE or EPSS data was supplied.
