CVE-2026-60310: Oracle E-Business Suite Auth Bypass Flaw

CVE-2026-60310 Overview

CVE-2026-60310 affects the Oracle Performance Management product within Oracle E-Business Suite, specifically the Appraisals component. Supported versions 12.2.3 through 12.2.15 are affected. A low-privileged attacker with network access via HTTP can exploit this weakness to compromise Oracle Performance Management. Successful exploitation permits unauthorized update, insert, or delete operations on a subset of accessible data, along with unauthorized read access to a limited data set. The vulnerability is classified under [CWE-284] Improper Access Control.

Critical Impact
Authenticated attackers can modify and read Oracle Performance Management data over the network without user interaction, undermining data integrity in HR appraisal workflows.

Affected Products

Oracle E-Business Suite - Oracle Performance Management 12.2.3 through 12.2.15
Component: Appraisals
Deployments exposing Oracle E-Business Suite HTTP interfaces to internal or external networks

Technical Details for CVE-2026-60310

Vulnerability Analysis

The flaw resides in the Appraisals component of Oracle Performance Management, part of the Oracle E-Business Suite (EBS) HR module. Improper access control ([CWE-284]) allows an authenticated user holding minimal privileges to perform operations beyond their assigned role. The scope is unchanged, meaning the attacker cannot pivot beyond the vulnerable component, yet the impact spans both confidentiality and integrity within Performance Management data. Availability is not affected. The EPSS probability sits at 0.15%, reflecting a low current exploitation likelihood, though authenticated exposure inside enterprise EBS deployments remains a valid concern.

Root Cause

The underlying weakness is improper access control in the Appraisals workflow. Authorization checks fail to correctly validate whether the authenticated principal has permission to read or modify targeted records. This class of flaw commonly manifests as missing server-side authorization on data-modifying endpoints or reliance on client-supplied identifiers without ownership validation.

Attack Vector

An attacker requires network reachability to the Oracle E-Business Suite HTTP interface and a valid low-privileged application account. No user interaction is needed. The attacker issues HTTP requests to the Appraisals functionality to read, insert, update, or delete records that should be inaccessible to their role. Because Oracle EBS is frequently exposed to internal users across large enterprises, the pool of potential low-privileged attackers is substantial.

Oracle has not published exploitation specifics. Refer to the Oracle Critical Patch Update - July 2026 advisory for authoritative remediation details.

Detection Methods for CVE-2026-60310

Indicators of Compromise

Unexpected HTTP requests to Oracle Performance Management Appraisals endpoints originating from accounts without HR responsibilities
Anomalous INSERT, UPDATE, or DELETE activity in Performance Management tables outside of documented business workflows
Access to appraisal records by user IDs that do not map to the record owner or reviewer chain

Detection Strategies

Review Oracle EBS FND audit logs and web access logs for Appraisals module requests correlated with low-privileged accounts
Enable database-level auditing on Performance Management schemas to capture DML operations and compare against expected application workflows
Baseline normal user-to-endpoint access patterns and alert on deviations targeting /OA_HTML/ Appraisals pages

Monitoring Recommendations

Forward Oracle EBS application, web tier, and database audit logs to a centralized SIEM for correlation
Alert on privilege-sensitive operations against Performance Management tables performed outside sanctioned HR service accounts
Track authentication anomalies such as unusual session times or source IPs for accounts with EBS access

How to Mitigate CVE-2026-60310

Immediate Actions Required

Apply the July 2026 Oracle Critical Patch Update for Oracle E-Business Suite to all instances running versions 12.2.3 through 12.2.15
Inventory user accounts with access to the Oracle Performance Management module and enforce least privilege
Restrict network exposure of Oracle E-Business Suite HTTP interfaces to authorized corporate networks only

Patch Information

Oracle addressed this issue in the July 2026 Critical Patch Update. Administrators should follow the guidance in the Oracle Critical Patch Update - July 2026 advisory and apply the corresponding Performance Management patches for versions 12.2.3 through 12.2.15. Verify patch installation in a non-production environment prior to production rollout.

Workarounds

Temporarily revoke access to the Appraisals functionality for non-essential users until patching is complete
Place Oracle EBS behind an authenticating reverse proxy or web application firewall to constrain access to the Appraisals URIs
Increase audit granularity on Performance Management tables to detect abuse while patch deployment is scheduled
