AnalysisAIv1 – Sep 15, 2026

Oracle BI Publisher (an Oracle Analytics reporting component) versions 8.2.0.0.0, 12.2.1.4.0 and 26.01.0.0.0 contain a flaw in the Web Server component that lets a low-privileged, network-positioned attacker read critical data and alter or delete a subset of records through HTTP, with impact potentially extending beyond the vulnerable component to other Oracle Analytics products. Oracle rates it CVSS 3.1 8.5 (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:L/A:N) in its October-lineage Security Alert. No public exploit code, EPSS score, or CISA KEV entry was present in the supplied intelligence, so active exploitation is unconfirmed.
