Security.io Intelligence Desk · Thursday, 6 August 2026
Executive consequence
Oracle PeopleSoft Enterprise PeopleTools 8.61 and 8.62 remain an incident-assessment priority because CVE-2026-35273 permits unauthenticated remote code execution and fresh reporting continues to characterise exploitation as active.
Decision today
Inventory every PeopleTools 8.61 and 8.62 deployment.

Inventory adaptive detectors that retrain after deployment.
