Oracle PeopleSoft CVE-2026-35273 Actively Exploited via WAF Bypass

  • Engineer — Act: CVE-2026-35273 (CVSS 9.8, unauthenticated RCE) is CISA KEV-listed with a public GitHub PoC and confirmed mass exploitation; patch Oracle PeopleSoft immediately and audit web-accessible directories for newly created web shells.
  • SOC/IR — Act: ShinyHunters-linked actors are actively deploying web shells post-exploitation, indicating persistent footholds; sweep PeopleSoft-adjacent hosts for web shell artifacts and hunt for anomalous outbound connections from PeopleSoft servers since this campaign began.
  • Leader — Act: A mass global campaign by a known data-exfiltration actor targeting PeopleSoft — widely used for HR and ERP — warrants same-week action; confirm whether PeopleSoft is in your environment, verify patch status with engineering, and prepare a brief for leadership given ShinyHunters’ history of large-scale data theft.
