CVE-2026-70782: Oracle Labor Distribution Auth Bypass

CVE-2026-70782 Overview

CVE-2026-70782 is a high-severity vulnerability in the Oracle Labor Distribution product, a component of Oracle E-Business Suite. The flaw resides in the Internal Operations component and affects supported versions 12.2.3 through 12.2.15. A low-privileged attacker with network access over HTTP can exploit this vulnerability without user interaction. Successful exploitation allows unauthorized creation, deletion, or modification of critical data. Attackers can also gain unauthorized read access to all data accessible through Oracle Labor Distribution. Oracle addressed the issue in its August 2026 Critical Patch Update.

Critical Impact
Authenticated remote attackers can read, modify, or delete all data accessible through Oracle Labor Distribution, threatening the confidentiality and integrity of payroll and labor cost allocation records.

Affected Products

Oracle E-Business Suite - Oracle Labor Distribution 12.2.3
Oracle E-Business Suite - Oracle Labor Distribution versions 12.2.4 through 12.2.14
Oracle E-Business Suite - Oracle Labor Distribution 12.2.15

Technical Details for CVE-2026-70782

Vulnerability Analysis

The vulnerability affects the Internal Operations component of Oracle Labor Distribution, a module within Oracle E-Business Suite that manages effort reporting and labor cost distribution. An authenticated attacker with low privileges can send crafted HTTP requests to interact with the affected component. Successful exploitation compromises confidentiality and integrity but does not affect availability.

The attack requires no user interaction and has low complexity. Because Oracle Labor Distribution handles payroll allocation and grant-funded effort tracking, unauthorized access exposes sensitive financial data. Modification of records could distort labor cost allocations, disrupt effort certification workflows, and affect regulatory reporting for institutions that rely on the module.

Root Cause

Oracle has not published detailed root cause information for CVE-2026-70782. The advisory describes the flaw as an easily exploitable weakness in the Internal Operations component reachable over HTTP by a low-privileged user. See the Oracle Security Alert for vendor-supplied technical context.

Attack Vector

Exploitation requires network access to an HTTP endpoint exposed by the Oracle E-Business Suite instance. The attacker must hold valid low-privileged credentials to the application. From that position, a crafted request to the affected Internal Operations functionality grants unauthorized access to Oracle Labor Distribution data. No victim interaction is required, and the scope remains unchanged, meaning the impact is confined to resources managed by the vulnerable component.

No public proof-of-concept exploit is available at the time of publication, and the vulnerability is not listed on the CISA Known Exploited Vulnerabilities catalog.

Detection Methods for CVE-2026-70782

Indicators of Compromise

Unexpected HTTP requests from authenticated low-privileged accounts targeting Oracle Labor Distribution Internal Operations endpoints.
Anomalous read, modify, or delete operations on labor distribution records outside normal business hours or user workflows.
Audit log entries showing bulk data access by accounts that historically interact with a small dataset.

Detection Strategies

Enable and review Oracle E-Business Suite auditing (FND_LOGIN, FND_LOG_MESSAGES) for the Labor Distribution schema.
Correlate application-tier HTTP access logs with database query patterns to spot unauthorized data enumeration.
Baseline expected behavior of low-privileged Labor Distribution users and alert on deviations in request volume or record access.

Monitoring Recommendations

Forward Oracle E-Business Suite application, middleware, and database audit logs to a central SIEM for correlation.
Monitor for changes to critical Labor Distribution tables and configuration objects, including unexpected DML activity.
Track privileged account usage and failed authorization attempts against Internal Operations URIs.

How to Mitigate CVE-2026-70782

Immediate Actions Required

Apply the Oracle Critical Patch Update from August 2026 to all Oracle E-Business Suite environments running Labor Distribution versions 12.2.3 through 12.2.15.
Inventory Oracle E-Business Suite instances to confirm exposure, prioritizing internet-reachable deployments.
Rotate credentials for low-privileged accounts if suspicious activity is detected in Labor Distribution audit logs.

Patch Information

Oracle addressed CVE-2026-70782 in the August 2026 Critical Patch Update. Administrators should review the Oracle Security Alert and apply the recommended patch bundle to all affected 12.2.x installations. Restart affected middle-tier and application services after patching to ensure the fix is loaded.

Workarounds

Restrict network access to the Oracle E-Business Suite application tier using firewall rules and reverse-proxy allowlists.
Review and tighten role assignments so only required users hold access to Oracle Labor Distribution responsibilities.
Place the application behind a web application firewall (WAF) to filter anomalous HTTP requests targeting the Internal Operations component until patching is complete.

bash

# Example: restrict access to the EBS application tier at the network layer
# Allow only trusted internal subnets to reach the HTTP listener
iptables -A INPUT -p tcp --dport 8000 -s 10.10.0.0/16 -j ACCEPT
iptables -A INPUT -p tcp --dport 8000 -j DROP
