AnalysisAIv1 – Sep 16, 2026

Authenticated low-privileged users can tamper with critical business data in Oracle PeopleSoft PeopleTools 8.61 through 8.63 by abusing the Integration Broker component over HTTP. Oracle rates the flaw 7.7 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:H/A:N), an integrity-only impact that can also propagate into other applications attached to the same integration fabric. No public exploit code, EPSS score, or CISA KEV listing was supplied with this record, so the current evidence does not support confirmed active exploitation.
