> Multiple vulnerabilities in Oracle PeopleSoft allow remote code execution, data breach, and denial of service.

Oracle PeopleSoft contains multiple security vulnerabilities affecting several product versions and modules. These flaws enable remote attackers to execute arbitrary code, compromise data confidentiality and integrity, and trigger denial-of-service conditions. The vulnerabilities affect PeopleSoft Enterprise PeopleTools versions 8.61 through 8.63, CC Common Application Objects version 9.2, and several regional variants including FIN Engineering Brazil, FIN Inventory Brazil, and PRTL Interaction Hub version 9.1. Affected organizations must apply the security patches referenced in Oracle's September 2026 security bulletin (cspusep2026) to remediate the identified CVEs.

## Detection guidance (public sample)

### PeopleSoft or WebLogic Java Process Spawning Windows Shell

ATT&CK: T1190

Java process hosting PeopleSoft/WebLogic spawning cmd, PowerShell or LOLBins, indicating web-tier RCE exploitation. Auto-generated starting point — validate and tune in your environment before deploying. IOC matches can false-positive on shared infrastructure and decay as adversary infrastructure rotates.
