Oracle PeopleSoft Enterprise SCM Strategic Sourcing: Privilege escalation via HTTP
Summary
Oracle PeopleSoft Enterprise SCM Strategic Sourcing version 9.2 contains a vulnerability that allows an attacker with a low-privileged account and network access over HTTP to take over the application. The CVSS score is 8.8 and the impacts affect confidentiality, integrity and availability. The attack requires valid low-privilege credentials, so exposed supplier or partner portals with weak or shared accounts carry the highest risk.
Affected

- Other versions: not listed as affected in the sources reviewed
Fixed in
- Unknown. No fixed build or patch ID was found in the sources reviewed. Check the Oracle October 2026 CPU advisory (PeopleSoft table) and My Oracle Support.
Workaround

- No public proof of concept or in-the-wild exploitation found.
Our recommendation
- Check whether PeopleSoft SCM Strategic Sourcing 9.2 is in use and whether its portal is internet-facing.
- If in use, apply the Oracle October 2026 CPU patch for PeopleSoft once the 9.2 patch ID is confirmed.
- Review and reduce accounts with access to the portal and enable HTTP access logging.
- Keep PeopleSoft patched in general, as other PeopleSoft flaws are being exploited.
