AnalysisAIv1 – Sep 15, 2026

Local takeover of Oracle PeopleSoft Enterprise PeopleTools (Cube Manager component) is possible for a low-privileged user who can log on to the infrastructure hosting the product, affecting versions 8.61 through 8.63. Oracle scores this 7.0 (CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H), reflecting a difficult-to-exploit but fully compromising flaw that yields high confidentiality, integrity and availability impact on the PeopleTools instance itself. No public exploit code or CISA KEV listing was identified at time of analysis, so the immediate threat is limited to actors who already hold a valid low-privileged account and interactive access to the PeopleSoft application tier.
