AnalysisAIv1 – Sep 15, 2026

Oracle PeopleSoft Enterprise PRTL Interaction Hub 9.1 (Enterprise Portal component) permits a low-privileged user with HTTP access to the portal to read data well beyond their assigned role, exposing critical enterprise data and, because the flaw crosses a trust boundary, potentially data held in other PeopleSoft products reachable through the portal. Oracle scores it 7.7 (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N) — confidentiality-only with a scope change — and fixed it in the 2026 Critical Patch Update. No public exploit code and no CISA KEV entry were identified at time of analysis, and no EPSS score was supplied with the source data.
