CVE-2026-60691: Oracle Content Manager Auth Bypass Flaw

CVE-2026-60691 Overview

CVE-2026-60691 is a high-severity vulnerability in the Oracle Content Manager product of Oracle E-Business Suite, specifically within the Internal Operations component. The flaw affects supported versions 12.2.3 through 12.2.15. A low-privileged attacker with network access via HTTP can exploit the vulnerability to compromise Oracle Content Manager. Successful exploitation grants unauthorized creation, deletion, or modification of critical data, along with unauthorized read access to all Oracle Content Manager accessible data. Oracle addressed the issue in the July 2026 Critical Patch Update.

Critical Impact
Authenticated network attackers can read, modify, or delete all data accessible to Oracle Content Manager, impacting confidentiality and integrity of the Oracle E-Business Suite deployment.

Affected Products

Oracle E-Business Suite - Oracle Content Manager versions 12.2.3 through 12.2.15
Component: Internal Operations
Attack surface: HTTP-accessible Oracle Content Manager endpoints

Technical Details for CVE-2026-60691

Vulnerability Analysis

The vulnerability resides in the Internal Operations component of Oracle Content Manager, part of Oracle E-Business Suite. An authenticated attacker holding low-level privileges can send crafted HTTP requests to compromise the Content Manager instance. The attack requires no user interaction and has low attack complexity, making exploitation practical once network access and valid credentials are available.

Successful exploitation results in unauthorized read access and write access, including creation, deletion, and modification of data within the scope of Oracle Content Manager. Availability is not directly affected by this issue. However, integrity compromise of a content management system supporting enterprise business processes can cascade into downstream operational impact.

Root Cause

Oracle has not published detailed root cause information. Based on the CVSS metrics and the affected component, the flaw stems from insufficient authorization enforcement within HTTP-accessible functions of the Internal Operations subsystem. Low-privileged users can invoke operations that should be restricted to higher-privileged roles.

Attack Vector

The attack vector is network-based over HTTP. The attacker must authenticate with any low-privileged account on the Oracle E-Business Suite deployment. From there, the attacker issues crafted HTTP requests to Oracle Content Manager endpoints exposing the vulnerable Internal Operations functionality. No victim interaction is required. Refer to the Oracle Security Alert CPU July 2026 for vendor-authoritative technical details.

Detection Methods for CVE-2026-60691

Indicators of Compromise

Unexpected HTTP requests from low-privileged user sessions targeting Oracle Content Manager Internal Operations URLs.
Anomalous content creation, deletion, or modification events in Oracle Content Manager audit logs attributed to non-administrative accounts.
Bulk read operations against Content Manager repositories outside normal business hours or workflows.

Detection Strategies

Enable and review Oracle E-Business Suite audit logging for Content Manager transactions, focusing on operations executed by low-privileged accounts.
Deploy web application firewall (WAF) rules to log and inspect HTTP traffic to Oracle Content Manager endpoints for irregular request patterns.
Correlate authentication events with subsequent content operations to identify privilege boundary violations.

Monitoring Recommendations

Alert on repeated HTTP requests to Internal Operations endpoints originating from accounts that do not typically access those functions.
Monitor for spikes in create, delete, or modify operations against Oracle Content Manager objects.
Track outbound data volumes from the Oracle E-Business Suite tier to detect potential bulk exfiltration of content repository data.

How to Mitigate CVE-2026-60691

Immediate Actions Required

Apply the July 2026 Oracle Critical Patch Update to all Oracle E-Business Suite 12.2.3 through 12.2.15 environments running Oracle Content Manager.
Inventory low-privileged Oracle E-Business Suite accounts and enforce credential rotation for accounts with weak or shared passwords.
Restrict network access to Oracle Content Manager HTTP endpoints to trusted internal networks only.

Patch Information

Oracle published the fix in the Oracle Critical Patch Update Advisory - July 2026. Administrators should apply the CPU to all affected 12.2.x deployments following Oracle's standard patch application procedure. Validate patch installation using Oracle's patch inventory tools after deployment.

Workarounds

Place Oracle E-Business Suite behind a reverse proxy or WAF that restricts access to Internal Operations paths pending patch application.
Disable or limit Oracle Content Manager functionality for user roles that do not require it, reducing the population of accounts that could exploit the flaw.
Enforce network segmentation so only authorized administrative subnets can reach the Content Manager interface.

bash

# Example: restrict access to Oracle Content Manager endpoints via nginx reverse proxy
location /OA_HTML/OracleContentManager/ {
    allow 10.10.20.0/24;   # admin subnet
    deny  all;
    proxy_pass http://ebs-backend;
}
