CVE-2026-60736: Oracle E-Business Auth Bypass Flaw

CVE-2026-60736 Overview

CVE-2026-60736 affects the Oracle E-Business Intelligence product within Oracle E-Business Suite, specifically the Definition component. Supported versions 12.2.3 through 12.2.15 are affected. The flaw allows a low-privileged attacker with network access via HTTP to compromise Oracle E-Business Intelligence. Successful exploitation results in unauthorized creation, deletion, or modification of critical data, and unauthorized access to all Oracle E-Business Intelligence accessible data. Oracle disclosed the issue in the July 2026 Critical Patch Update.

Critical Impact
Authenticated network attackers can read and modify all data accessible to Oracle E-Business Intelligence, undermining the confidentiality and integrity of enterprise reporting data.

Affected Products

Oracle E-Business Suite — E-Business Intelligence 12.2.3
Oracle E-Business Suite — E-Business Intelligence versions 12.2.4 through 12.2.14
Oracle E-Business Suite — E-Business Intelligence 12.2.15

Technical Details for CVE-2026-60736

Vulnerability Analysis

The vulnerability resides in the Definition component of Oracle E-Business Intelligence, part of the Oracle E-Business Suite reporting stack. An authenticated attacker holding low-privilege application credentials can send crafted HTTP requests to the affected endpoints. Oracle's advisory indicates the flaw is easily exploitable and does not require user interaction. Successful attacks yield unauthorized read access as well as unauthorized create, delete, and modify operations against data reachable by the E-Business Intelligence tier.

The scope of impacted data covers all records accessible to the Oracle E-Business Intelligence product, which frequently includes consolidated financial, operational, and business reporting information sourced from Oracle E-Business Suite modules. Availability is not affected according to Oracle.

Root Cause

Oracle has not published detailed root-cause information beyond identifying the Definition component of Oracle E-Business Intelligence as the affected subsystem. The advisory characterizes the issue as an access-control weakness reachable over HTTP by any authenticated E-Business Suite user, indicating insufficient authorization enforcement on Definition-related functionality. See the Oracle Critical Patch Update - July 2026 for the vendor advisory.

Attack Vector

Exploitation occurs remotely over HTTP against an internet-reachable or intranet-reachable Oracle E-Business Suite deployment. The attacker must already possess valid low-privilege credentials for the application. Once authenticated, the attacker interacts with the vulnerable Definition endpoints to read or manipulate business intelligence data outside of their assigned authorization scope. No user interaction is required, and attack complexity is low.

No public proof-of-concept exploit code is available at the time of publication. Oracle has not reported active exploitation, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.

Detection Methods for CVE-2026-60736

Indicators of Compromise

Unexpected HTTP requests from low-privileged E-Business Suite accounts targeting Oracle E-Business Intelligence Definition URLs
Anomalous create, update, or delete operations against E-Business Intelligence definition objects outside normal business hours
Audit log entries showing a single application user accessing an unusually broad set of Definition records

Detection Strategies

Enable and review Oracle E-Business Suite Sign-On Audit and Page Access Tracking to identify sessions issuing high volumes of Definition requests
Correlate application-tier access logs with database audit records to detect unauthorized data modifications originating from the E-Business Intelligence tier
Baseline typical Definition component usage per role and alert on deviations from that baseline

Monitoring Recommendations

Forward Oracle E-Business Suite application, middle-tier, and database audit logs to a centralized SIEM for correlation
Monitor authentication events for low-privileged accounts that begin accessing E-Business Intelligence functionality for the first time
Track HTTP request patterns to the Oracle HTTP Server for anomalous request volumes targeting oracle.apps.bis URLs

How to Mitigate CVE-2026-60736

Immediate Actions Required

Apply the July 2026 Oracle Critical Patch Update to all Oracle E-Business Suite environments running versions 12.2.3 through 12.2.15
Inventory all Oracle E-Business Intelligence deployments and confirm patch levels against the Oracle CPU advisory
Review and reduce the number of accounts holding access to E-Business Intelligence functionality

Patch Information

Oracle addressed CVE-2026-60736 in the Oracle Critical Patch Update - July 2026. Apply the vendor-supplied patch for Oracle E-Business Suite 12.2 to remediate the vulnerability. Oracle recommends staying on the most recent Critical Patch Update to receive the latest security fixes.

Workarounds

Restrict network access to Oracle E-Business Suite HTTP endpoints to trusted corporate networks and VPN users until patching is complete
Disable or restrict access to the Oracle E-Business Intelligence Definition component for user roles that do not require it
Enforce strong authentication and rotate credentials for low-privileged accounts that could be leveraged as an initial foothold
