Exploitation Conditions

No special conditions - remote unauthenticated exploitation over HTTP against Oracle PeopleSoft Enterprise FIN Common Objects Argentina 9.1 (eProcurement component); the CVSS vector AV:N/AC:L/PR:N/UI:N confirms no authentication, no user interaction, and low attack complexity. What LIMITS exploitation is deployment scope rather than technical prerequisites: the target must be a PeopleSoft installation running the Argentine financials localization at version 9.1 with the eProcurement/FIN Common Objects Argentina web endpoint network-reachable to the attacker. Organizations that do not deploy this specific Argentina localization module, or that restrict the PIA endpoints to internal networks/VPN, are not realistically exposed despite the high CVSS.

Impact

Signals are largely consistent and point to a genuine high priority: the CVSS 3.1 vector AV:N/AC:L/PR:N/UI:N yields a 9.1 base score, meaning remote, low-complexity, unauthenticated exploitation with no user interaction, and Oracle explicitly labels it 'easily exploitable.' High confidentiality and integrity impact (C:H/I:H) with no availability impact (A:N) is typical of a data-exposure/manipulation bug rather than a crash or RCE. Countervailing factors temper urgency: there is no CISA KEV listing (no confirmed active exploitation), no public POC identified, no EPSS score provided in the input, and no SSVC decision data supplied - so probability-of-exploitation and automatability cannot be quantified from the available data. The mitigating real-world factor is footprint: this is the Argentina financial localization module of PeopleSoft, so only organizations that deploy PeopleSoft Financials with the Argentine localization at version 9.1 are exposed. Net: treat as high-priority patching for affected deployments given the trivial exploitability and total data compromise, while recognizing exploitation-in-the-wild is unproven.

Exploit ScenarioDerived

An attacker who can reach the PeopleSoft eProcurement HTTP endpoint sends crafted requests that bypass authentication, then reads or tampers with financial procurement data (vendors, orders, critical records) belonging to the FIN Common Objects Argentina module. Because no authentication, user interaction, or special conditions are required and complexity is low, the attack can be scripted and repeated; no public POC has been identified at time of analysis, so exploitation would require independent development.

AnalysisAIv1 – Jul 22, 2026

Unauthorized data compromise in Oracle PeopleSoft Enterprise FIN Common Objects Argentina 9.1 (eProcurement component) allows a remote, unauthenticated attacker over HTTP to read, create, delete, or modify all data accessible to the module. The CVSS 3.1 base score is 9.1 (C:H/I:H, no availability impact) and the flaw is described by Oracle as easily exploitable, with an "Authentication Bypass" tag reinforcing the PR:N vector. No public exploit is identified at time of analysis and it is not listed in CISA KEV; a fix ships in the Oracle Critical Patch Update of July 2026.

RemediationAI

Apply the fixes from the Oracle Critical Patch Update of July 2026 (patch available per vendor advisory: https://www.oracle.com/security-alerts/cpujul2026.html) - Oracle does not publish a discrete point-release version number for this component, so identify the specific PeopleSoft PeopleTools/PUM patch mapped to CVE-2026-61238 within that CPU and apply it. Oracle strongly recommends applying CPU patches without delay for unauthenticated network-exploitable issues. Until patching is complete, reduce exposure by restricting network reachability of the PeopleSoft Internet Architecture endpoints for the eProcurement/FIN Common Objects Argentina module to trusted internal networks or via VPN, and place the PIA web tier behind a WAF or reverse proxy that enforces authenticated sessions on the affected servlet paths; the trade-off is that overly broad access restrictions may block legitimate remote procurement users, so scope the controls to the affected module rather than the whole PeopleSoft footprint. Monitor web/application logs for anomalous unauthenticated requests to eProcurement endpoints as a detective control.

Technical ContextAI · show details

The affected software is Oracle PeopleSoft, an enterprise ERP/HCM/Financials platform, specifically the FIN Common Objects Argentina localization module served through the eProcurement component. PeopleSoft applications are delivered over HTTP via PeopleSoft Internet Architecture (PIA) web servlets, so a network-reachable HTTP endpoint is the exposed surface. Oracle does not assign a CWE (CWE: N/A), but the vendor 'Authentication Bypass' tag combined with the CVSS PR:N metric points to a root cause in the authorization/authentication enforcement path - a request handler that fails to require or correctly validate a session before granting access to sensitive eProcurement data operations. Because scope is unchanged (S:U), impact is confined to the data and privileges of the vulnerable PeopleSoft component itself rather than the underlying host.

DescriptionCVE.org

Vulnerability in the PeopleSoft Enterprise FIN Common Objects Argentina product of Oracle PeopleSoft (component: eProcurement). 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 Argentina. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all PeopleSoft Enterprise FIN Common Objects Argentina accessible data as well as unauthorized access to critical data or complete access to all PeopleSoft Enterprise FIN Common Objects Argentina accessible data. CVSS 3.1 Base Score 9.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N).

Executive ViewAI

Why It Matters

Oracle PeopleSoft Enterprise FIN Common Objects Argentina 9.1 (eProcurement module) contains a critical unauthenticated remote vulnerability enabling attackers to read, create, delete, and modify all procurement and financial data. Organizations using this component should assume vendor master records, purchase orders, and payment information are at risk of compromise without immediate patching. This authentication bypass poses an emergency-level threat to procurement operations and financial control environments.

Business Impact: Severe
