Oracle released emergency mitigations for CVE-2026-35273, a critical unauthenticated remote code execution zero-day in PeopleSoft PeopleTools 8.61 and 8.62 that ShinyHunters exploited to steal data from 300 instances across more than 100 organizations. The flaw carries a 9.8 CVSS score and highlights ongoing risks to enterprise platforms hosting sensitive corporate data.
ShinyHunters used the zero-day to breach over 100 organizations.
The group left ransom notes on compromised instances and claimed to use a gadget chain of old and zero-day flaws.
Enterprise security teams should treat this as an immediate patching priority and scan logs for the listed IPs, as the gap between zero-day disclosure and widespread exploitation continues to shrink for legacy enterprise suites.
