Lifecycle Timeline
2DescriptionCVE.org
Vulnerability in the PeopleSoft Enterprise HCM Global Payroll Switzerland product of Oracle PeopleSoft (component: Global Payroll for Switzerland). The supported version that is affected is 9.2. Difficult to exploit vulnerability allows low privileged attacker with network access via HTTP to compromise PeopleSoft Enterprise HCM Global Payroll Switzerland. While the vulnerability is in PeopleSoft Enterprise HCM Global Payroll Switzerland, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all PeopleSoft Enterprise HCM Global Payroll Switzerland accessible data as well as unauthorized access to critical data or complete access to all PeopleSoft Enterprise HCM Global Payroll Switzerland accessible data. CVSS 3.1 Base Score 8.2 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:N).
AnalysisAI
Cross-privilege data compromise in Oracle PeopleSoft Enterprise HCM Global Payroll for Switzerland 9.2 lets a low-privileged, network-based attacker read, alter, or delete critical payroll data and, because of a scope change, impact other integrated PeopleSoft products beyond the vulnerable module. The flaw is rated CVSS 3.1 8.2 (high) with confidentiality and integrity impact but no availability impact, and it is difficult to exploit (AC:H). No public exploit identified at time of analysis and it is not listed in CISA KEV; the fix is delivered through the Oracle July 2026 Critical Patch Update.
Technical ContextAI
The affected component is the Global Payroll for Switzerland module within Oracle PeopleSoft Enterprise HCM, a large Java/PeopleTools-based ERP suite that manages HR and country-specific payroll processing over an HTTP/PIA (PeopleSoft Internet Architecture) web front end. Oracle assigned no CWE, but the intelligence tag 'Authentication Bypass' combined with the CVSS scope change (S:C) points to a flaw where an authenticated low-privilege user crosses a trust or authorization boundary, allowing their actions to affect data and components outside the Swiss payroll module's own security authority. No CPE strings were provided; affected-product identification relies on the Oracle CPU advisory and the ENISA EUVD record (EUVD-2026-47024), which both scope the issue to version 9.2 of this module.
RemediationAI
Apply the fix from the Oracle July 2026 Critical Patch Update (https://www.oracle.com/security-alerts/cpujul2026.html), which is the primary vendor-supported remediation - Patch available per vendor advisory; Oracle CPUs bundle the required PeopleTools/HCM patches for version 9.2 and no standalone fix version was published separately in the input data, so identify the exact bundle for your maintenance level in the CPU matrix. Because exploitation requires network HTTP access with low privileges, compensating controls until patching include restricting network reach to the PeopleSoft Internet Architecture (PIA) web tier so only trusted internal and VPN clients can reach it (trade-off: may break remote employee self-service payroll access), tightening role and permission-list assignments for the Global Payroll for Switzerland pages to shrink the population of low-privilege accounts that can reach the vulnerable code (trade-off: administrative overhead and possible workflow disruption), and enabling detailed audit logging and monitoring of payroll data changes to detect unauthorized create/modify/delete activity. Do not treat these workarounds as a permanent substitute for the CPU patch.
