Senserva AI Opinion for CVE-2026-35273
This flaw lets an unauthenticated attacker fully take over PeopleSoft Enterprise PeopleTools because a critical function is missing authentication entirely, meaning no credentials or user interaction are required. Organizations running PeopleSoft for HR, payroll, or financials are exposed, and with a 94% EPSS score, confirmed exploitation in CISA KEV as of 2026-06-12, and documented ransomware use, this is being weaponized right now against internet-facing deployments.
Do this: Apply Oracle's patch for CVE-2026-35273 to all PeopleTools instances immediately and pull any internet-exposed PeopleSoft portals behind a VPN or firewall until patched.
