CVE-2026-70815: Oracle E-Business Suite Auth Bypass Flaw

CVE-2026-70815 Overview

CVE-2026-70815 is a high-severity vulnerability in the Oracle Internet Procurement Connector product of Oracle E-Business Suite, within the Internal Operations component. Affected versions span 12.2.3 through 12.2.15. An attacker with low privileges and network access via HTTP can exploit the flaw to compromise the Oracle Internet Procurement Connector. Successful exploitation grants unauthorized creation, deletion, or modification of critical data, and unauthorized read access to all data accessible by the connector. Oracle addressed this issue in the August 2026 Critical Patch Update.

Critical Impact
Authenticated remote attackers can read and modify all data accessible to the Oracle Internet Procurement Connector, exposing procurement records and internal operations data across the E-Business Suite deployment.

Affected Products

Oracle E-Business Suite — Oracle Internet Procurement Connector 12.2.3
Oracle E-Business Suite — Oracle Internet Procurement Connector versions 12.2.4 through 12.2.14
Oracle E-Business Suite — Oracle Internet Procurement Connector 12.2.15

Technical Details for CVE-2026-70815

Vulnerability Analysis

The vulnerability resides in the Internal Operations component of the Oracle Internet Procurement Connector, part of Oracle E-Business Suite. An authenticated attacker with a low-privileged account can reach the vulnerable endpoint over HTTP without user interaction. Exploitation permits unauthorized read and write access to all data the connector processes, including procurement transactions, supplier records, and internal workflow data. Availability of the service is not directly affected, but data integrity and confidentiality across the connector's scope are fully compromised. The current EPSS probability for exploitation is 0.392%.

Root Cause

Oracle has not published detailed root-cause analysis for CVE-2026-70815. Based on the CVSS profile and the affected component, the flaw permits authenticated HTTP requests to bypass authorization checks that should restrict access to internal operations functionality. Oracle's August 2026 Critical Patch Update advisory is the authoritative reference for technical details.

Attack Vector

Exploitation requires network access to the Oracle E-Business Suite HTTP interface and a valid low-privileged account. The attack does not require user interaction and does not involve chaining to other vulnerabilities. An attacker with any authenticated foothold in the E-Business Suite environment can invoke the vulnerable Internal Operations functionality to read or alter data owned by the Internet Procurement Connector. See the Oracle Security Alert for August 2026 for vendor-supplied technical context.

No public proof-of-concept exploit code has been released for this vulnerability. The vulnerability is described in prose here because no verified exploitation code exists in the public domain.

Detection Methods for CVE-2026-70815

Indicators of Compromise

Unexpected HTTP requests from low-privileged E-Business Suite user accounts targeting Internet Procurement Connector endpoints under the Internal Operations component.
Anomalous procurement record creation, deletion, or modification events performed by accounts that do not normally interact with procurement workflows.
Bulk read operations against procurement or supplier data outside of normal business hours or from unusual source addresses.

Detection Strategies

Enable and review Oracle E-Business Suite audit logs for FND_LOG_MESSAGES and page access logs tied to the Internet Procurement Connector.
Correlate authenticated HTTP session data with database-level DML activity on procurement tables to identify unauthorized writes.
Alert on privilege-to-action mismatches where low-privileged users trigger Internal Operations functions.

Monitoring Recommendations

Forward Oracle E-Business Suite application and database audit logs to a centralized SIEM for correlation and long-term retention.
Baseline normal Internet Procurement Connector usage per user role and alert on statistically significant deviations.
Monitor the Oracle HTTP Server (OHS) access logs for repeated requests to Internal Operations URIs from a single session.

How to Mitigate CVE-2026-70815

Immediate Actions Required

Apply the fixes from the Oracle August 2026 Critical Patch Update to all Oracle E-Business Suite instances running Internet Procurement Connector versions 12.2.3 through 12.2.15.
Inventory all E-Business Suite environments, including non-production and disaster recovery instances, and confirm patch coverage.
Rotate credentials for low-privileged accounts that had network access to the vulnerable HTTP endpoints prior to patching.

Patch Information

Oracle released the fix for CVE-2026-70815 as part of the August 2026 Critical Patch Update. Refer to the Oracle Security Alert for August 2026 for patch numbers, prerequisite bundle information, and Oracle Support Document references. Apply the patch to all instances of Oracle Internet Procurement Connector in the affected version range.

Workarounds

Restrict network access to the Oracle E-Business Suite HTTP endpoints exposing the Internet Procurement Connector using firewall rules or reverse proxy allowlists until patching is complete.
Review and tighten user provisioning for low-privileged E-Business Suite accounts to minimize the population of accounts that can reach the vulnerable component.
Enable enhanced auditing on the Internet Procurement Connector to increase detection fidelity while patch rollout proceeds.
