Exploitation Conditions

Exploitation requires a reachable Oracle E-Business Suite deployment running the Public Sector Financials (International) module on versions 12.2.6 through 12.2.15, network HTTPS access to the EBS application tier, and a valid low-privileged EBS user account (PR:L) - pure unauthenticated exploitation is not indicated by the CVSS vector despite the 'Authentication Bypass' tag in the input. No user interaction is required (UI:N) and attack complexity is low (AC:L), so once an attacker holds any EBS credentials and network reachability, no further victim action or special timing is needed. Limiting factors include: organizations that do not license or deploy the Public Sector Financials (International) module are not exposed, deployments where the EBS application tier is not internet-facing significantly reduce attacker reach, and impact is confidentiality-only so the vulnerability cannot directly be used to modify financial data or cause denial of service.

Impact

The CVSS 3.1 score of 7.7 is driven by network attack vector, low complexity, low privileges, no user interaction, scope change, and high confidentiality impact with no integrity or availability impact (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N) - meaning any authenticated EBS user, including very low-privileged ones, can read sensitive data they should not access. No EPSS score was provided in the input, the CVE is not listed in CISA KEV, and no public proof-of-concept was indicated, so the practical exploitation likelihood is currently unknown but not confirmed as actively exploited. The combination of 'easily exploitable' language from Oracle plus PR:L (any low-privileged account suffices) plus scope change makes this a meaningful priority for organizations running EBS 12.2.x in public-sector contexts, even though confidentiality-only impact and the requirement of a valid EBS account limit it below an unauthenticated RCE. The 'Authentication Bypass' tag supplied with the input partially conflicts with the CVSS vector (PR:L implies authentication is required, not bypassed) - defenders should treat this as an authorization bypass rather than an authentication bypass and verify against the Oracle advisory.

Exploit ScenarioDerived

A contractor or low-privileged internal user with any valid Oracle E-Business Suite account authenticates over HTTPS to the EBS application tier and invokes a crafted request against the Public Sector Financials (International) module, causing the Authorization component to grant access to data the account should not see. Because the CVSS scope is changed, the unauthorized read can extend to data managed by other components of the EBS deployment, potentially exposing financial records, vendor data, or personally identifiable information of citizens and employees. No public exploit identified at time of analysis, so an attacker would need to develop the request pattern from the advisory and product knowledge.

AnalysisAIv1 – May 28, 2026

Unauthorized data access in Oracle Public Sector Financials (International), a module of Oracle E-Business Suite versions 12.2.6 through 12.2.15, allows low-privileged remote attackers to read sensitive data across module boundaries due to a flaw in the Authorization component. The scope-changed CVSS 7.7 vector indicates exploitation can affect resources beyond the vulnerable component itself, expanding the blast radius to other EBS data. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.

RemediationAI

Apply the patches delivered in Oracle's May 2026 Critical Patch Update as documented at https://www.oracle.com/security-alerts/cspumay2026.html; the input data confirms patch availability via this advisory but does not specify an exact post-patch version number, so administrators should match the CPU patch identifier to their specific 12.2.x baseline. Until the CPU is applied, restrict network access to the EBS application tier so that only trusted internal networks can reach HTTPS endpoints (this may break legitimate remote user access and integrations), tighten responsibility and menu assignments to minimize the population of users who hold any EBS account (since PR:L means even low-privileged users can exploit), and increase monitoring on EBS audit logs for unusual data access patterns from low-privilege accounts. Avoid disabling the Public Sector Financials (International) module entirely unless it is unused, as this will impact financial operations.

Technical ContextAI · show details

Oracle E-Business Suite (EBS) is a large enterprise resource planning (ERP) suite, and the Public Sector Financials (International) module provides financial management functionality tailored to government and public-sector organizations outside the US. The vulnerability sits in the Authorization component, meaning the flaw involves how the application enforces access decisions on authenticated sessions rather than how it authenticates users. Although no CWE was assigned by Oracle, the behavior - a low-privileged user reading data they should not see - is consistent with the broader CWE-285 (Improper Authorization) / CWE-863 (Incorrect Authorization) class. The CPE string cpe:2.3:a:oracle_corporation:oracle_public_sector_financials_(international) confirms the affected product family, and the scope-changed (S:C) CVSS vector indicates the authorization boundary that is bypassed lies between security contexts within the EBS deployment.

DescriptionCVE.org

Vulnerability in the Oracle Public Sector Financials (International) product of Oracle E-Business Suite (component: Authorization). Supported versions that are affected are 12.2.6-12.2.15. Easily exploitable vulnerability allows low privileged attacker with network access via HTTPS to compromise Oracle Public Sector Financials (International). While the vulnerability is in Oracle Public Sector Financials (International), attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Public Sector Financials (International) accessible data. CVSS 3.1 Base Score 7.7 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N).

Executive ViewAI

Why It Matters

Oracle Public Sector Financials module in EBS versions 12.2.6-12.2.15 contains an authorization flaw allowing low-privileged remote users to access sensitive financial data across module boundaries, creating enterprise-wide data exposure risk. Organizations running affected versions face immediate risk of unauthorized access to mission-critical public sector financial records without a vendor patch currently available.

Business Impact: High
Compensating Controls

No vendor-released patch identified at time of analysis. Interim mitigations: (1) Restrict low-privileged user roles from accessing Public Sector Financials module resources via role-based access controls; (2) implement application-level query auditing and alerting on cross-module data access attempts; (3) segment EBS environment network access where feasible to limit remote attacker reach; (4) monitor for suspicious data export activity by non-administrative accounts.
