Oracle PeopleSoft CVE-2026-35273: ShinyHunters Zero-Day
If you run PeopleTools 8.61 or 8.62 with PIA reachable from the internet, apply Oracle's fix and lock down the EMHub/PSIGW paths today, then hunt back to May 27, 2026.
Must act: PeopleSoft customers on PeopleTools 8.61 or 8.62, above all universities running Campus Solutions and any organization with PeopleSoft exposed to the internet.
Can relax: Organizations that do not run PeopleSoft, or whose PeopleSoft web tier is reachable only from internal networks and has been patched, are at much lower risk.
- Apply the remediation in Oracle's CVE-2026-35273 Security Alert for PeopleTools 8.61/8.62
- Disable the Environment Management Hub (EMHub) in multi-server setups, or remove the PSEMHUB application in single-server setups
- Block external access to /PSEMHUB/* and /PSIGW/HttpListeningConnector at the perimeter (non-breaking for normal PIA sessions, per Mandiant)
