CVE-2026-62482: Oracle Public Sector Financials Bypass

CVE-2026-62482 Overview

CVE-2026-62482 is a vulnerability in the Oracle Public Sector Financials product of Oracle E-Business Suite, specifically in the Internal Operations component. Supported versions 12.2.3 through 12.2.15 are affected. An authenticated attacker with low privileges and network access via HTTP can compromise the application. Successful exploitation allows unauthorized update, insert, or delete access to a subset of Oracle Public Sector Financials data, along with unauthorized read access to a limited data set. The vulnerability is categorized under [CWE-284] Improper Access Control.

Critical Impact
Authenticated network attackers can modify and read a subset of Oracle Public Sector Financials data through the Internal Operations component.

Technical Details for CVE-2026-62482

Vulnerability Analysis

The flaw resides in the Internal Operations component of Oracle Public Sector Financials, part of Oracle E-Business Suite. Improper access control ([CWE-284]) allows a low-privileged authenticated user to perform operations beyond their intended authorization scope. The attack traverses HTTP, meaning any user with network reachability to the application tier and valid low-privilege credentials can attempt exploitation. The scope remains unchanged, and the impact is limited to partial confidentiality and integrity effects with no availability impact.

Root Cause

The root cause is improper enforcement of access control decisions within the Internal Operations component. Access checks either fail to validate the requesting user's authorization for specific data operations or apply weaker checks than required. This gap enables data reads and modifications outside the caller's role boundary.

Attack Vector

Exploitation requires an authenticated session with low privileges and network access to the E-Business Suite HTTP endpoints. The attacker sends crafted HTTP requests to the Internal Operations component. No user interaction is required to complete the attack. Successful requests yield unauthorized read access to a subset of application data and unauthorized insert, update, or delete access to another subset.

No public proof-of-concept code or exploit tooling has been published for CVE-2026-62482. Refer to the Oracle Critical Patch Update July 2026 advisory for technical details.

Detection Methods for CVE-2026-62482

Indicators of Compromise

Unexpected HTTP requests to Internal Operations endpoints originating from user accounts that do not normally interact with Public Sector Financials modules.
Database audit records showing insert, update, or delete operations on Public Sector Financials tables performed by low-privileged application users.
Anomalous read queries returning records outside the accessing user's assigned responsibility or organization scope.

Detection Strategies

Enable Oracle E-Business Suite Sign-On Audit and Page Access Tracking to record which users invoke the Internal Operations functions.
Correlate application-tier HTTP access logs with database change auditing to identify data modifications lacking a corresponding legitimate workflow.
Baseline normal usage patterns per responsibility and alert on deviations, particularly bulk record access or off-hours modifications.

Monitoring Recommendations

Monitor FND_LOGINS, FND_LOGIN_RESPONSIBILITIES, and related audit tables for privilege usage inconsistent with assigned roles.
Forward E-Business Suite application, middle-tier, and database logs to a centralized analytics platform for correlation and retention.
Alert on repeated HTTP 4xx/5xx responses from Internal Operations URLs, which may indicate probing activity.

How to Mitigate CVE-2026-62482

Immediate Actions Required

Apply the July 2026 Oracle Critical Patch Update to all Oracle E-Business Suite instances running affected Public Sector Financials versions 12.2.3 through 12.2.15.
Inventory all E-Business Suite environments, including non-production, and confirm patch level for each.
Review user responsibilities and revoke access to Public Sector Financials modules for accounts that do not require it.

Patch Information

Oracle addressed CVE-2026-62482 in the Oracle Critical Patch Update July 2026. Administrators must download and apply the corresponding patch for their E-Business Suite 12.2 release level. Follow Oracle's standard procedure of applying the patch in a test environment before promoting to production, and validate custom extensions after patching.

Workarounds

Restrict network access to E-Business Suite HTTP endpoints using firewall rules, reverse proxies, or VPN-only access until patching is complete.
Enforce least privilege by auditing and tightening responsibilities associated with Internal Operations functions.
Enable Oracle E-Business Suite auditing on Public Sector Financials tables to detect unauthorized data changes during the patch window.
