CVE-2026-47033: Oracle Contracts Integration Auth Bypass

CVE-2026-47033 Overview

CVE-2026-47033 affects the Oracle Contracts Integration product within Oracle E-Business Suite, specifically the Internal Operations component. The flaw impacts supported versions 12.2.3 through 12.2.15. A low-privileged attacker with network access via HTTP can compromise Oracle Contracts Integration, though exploitation requires overcoming high attack complexity. The vulnerability is categorized under [CWE-284] Improper Access Control. Because the scope changes on successful exploitation, attacks may impact additional products beyond Oracle Contracts Integration itself, resulting in complete takeover.

Critical Impact
Successful exploitation leads to full takeover of Oracle Contracts Integration with cross-product scope impact affecting confidentiality, integrity, and availability.

Affected Products

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

Technical Details for CVE-2026-47033

Vulnerability Analysis

The vulnerability resides in the Internal Operations component of Oracle Contracts Integration. It is classified as [CWE-284] Improper Access Control. An authenticated attacker holding low privileges can send crafted HTTP requests to trigger the flaw. Successful exploitation results in takeover of Oracle Contracts Integration, with confidentiality, integrity, and availability all fully impacted.

The scope change indicator signals that the vulnerability crosses a trust boundary. Exploitation can extend impact to components beyond the vulnerable product itself, expanding the blast radius across the Oracle E-Business Suite deployment.

Root Cause

The root cause is improper access control within the Internal Operations component of Oracle Contracts Integration. Access decisions for privileged operations are not sufficiently enforced, allowing a low-privileged user to reach functionality or resources that should be restricted. Oracle has not published detailed technical internals in the Oracle Security Alert July 2026.

Attack Vector

The attack vector is network-based over HTTP. The attacker must hold valid low-privileged credentials in the target Oracle E-Business Suite environment. Attack complexity is high, meaning exploitation depends on conditions outside the attacker's direct control, such as timing, configuration, or specific application state. No user interaction is required. Refer to the Oracle Security Alert July 2026 for vendor guidance.

Detection Methods for CVE-2026-47033

Indicators of Compromise

Anomalous HTTP requests to Oracle Contracts Integration Internal Operations endpoints originating from low-privileged user sessions.
Unexpected privilege elevation or configuration changes within Oracle Contracts Integration audit logs.
Cross-module activity where a Contracts Integration session accesses resources in adjacent E-Business Suite products.

Detection Strategies

Enable and review Oracle E-Business Suite Sign-On Audit and page access tracking for the Contracts Integration module.
Correlate HTTP access logs from the Oracle HTTP Server tier with application-tier user session activity to identify privilege boundary crossings.
Baseline normal Internal Operations request patterns per user role and alert on deviations.

Monitoring Recommendations

Forward Oracle E-Business Suite application, database, and web tier logs to a centralized SIEM for retention and correlation.
Monitor for repeated failed authorization events preceding successful privileged actions in Contracts Integration.
Track outbound API and integration calls from Contracts Integration for signs of scope-crossing exploitation.

How to Mitigate CVE-2026-47033

Immediate Actions Required

Apply the July 2026 Critical Patch Update from Oracle to all Oracle E-Business Suite environments running versions 12.2.3 through 12.2.15.
Inventory all Oracle Contracts Integration deployments and confirm patch status against the Oracle Security Alert July 2026.
Review and restrict low-privileged accounts with access to Oracle Contracts Integration until patching is complete.

Patch Information

Oracle addressed CVE-2026-47033 in the July 2026 Critical Patch Update. Administrators should download and apply the fix through My Oracle Support following the guidance in the Oracle Security Alert July 2026. EPSS data as of 2026-07-23 reports an exploit probability of 0.345% at the 26.976 percentile, but this score can change once technical details become public.

Workarounds

Restrict network access to Oracle E-Business Suite HTTP endpoints to trusted internal networks and VPN users only.
Enforce least-privilege role assignments and remove unused low-privileged accounts that can reach Contracts Integration.
Place a web application firewall in front of the Oracle HTTP Server tier and block anomalous request patterns targeting Internal Operations.
