Vulnerability in the PeopleSoft Enterprise FIN Common Objects Brazil product of Oracle PeopleSoft (component: Staffing). The supported version that is affected is 9.1. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise PeopleSoft Enterprise FIN Common Objects Brazil. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all PeopleSoft Enterprise FIN Common Objects Brazil accessible data. CVSS 3.1 Base Score 7.5 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).
AnalysisAI
Unauthenticated information disclosure in Oracle PeopleSoft Enterprise FIN Common Objects Brazil 9.1 (Staffing component) lets a remote attacker send crafted HTTP requests to read critical data, potentially achieving complete access to all data accessible to the affected module. Oracle rates it easily exploitable with a CVSS 3.1 base score of 7.5, but the impact is confined to confidentiality (no integrity or availability effect). There is no public exploit identified at time of analysis and it is not listed in CISA KEV.
Technical ContextAI
The affected software is Oracle's PeopleSoft Enterprise Financials suite, specifically the FIN Common Objects Brazil localization package and its Staffing component, a web-facing enterprise ERP application typically deployed on PeopleSoft PIA (PeopleSoft Internet Architecture) with WebLogic/Tomcat front ends and a Tuxedo application tier. The vulnerability is reached over HTTP without authentication, indicating a flaw in a web-exposed servlet, iScript, or component-interface endpoint that fails to enforce access control on data retrieval. Oracle did not assign a CWE (listed as N/A), but the vendor's own tagging as 'Authentication Bypass' together with the confidentiality-only CVSS impact points to a missing-authorization / improper access control root cause (CWE-284/CWE-306 class) that exposes back-end financial data.
RemediationAI
Apply the fixes from Oracle's July 2026 Critical Patch Update (https://www.oracle.com/security-alerts/cpujul2026.html); the input does not include an exact patch/bundle number, so this is Patch available per vendor advisory - obtain the specific PeopleSoft PUM image / CPU patch for FIN Common Objects Brazil 9.1 from My Oracle Support and schedule it in your next maintenance window. Until patched, restrict network exposure of the PeopleSoft Internet Architecture web tier: place PIA behind a VPN or internal-only network segment, and use a WAF or reverse-proxy rule to restrict or block access to the vulnerable Staffing/Brazil-localization URLs and iScripts for untrusted sources (trade-off: may disrupt legitimate Brazil-locale users or integrations, so validate URL patterns before enforcing). Increase monitoring of PIA access logs for anomalous unauthenticated requests to the affected component. Do not rely on workarounds as a permanent fix, since the underlying access-control flaw remains until the CPU patch is applied.
