CVE-2026-60989: Oracle E-Business Suite Auth Bypass Flaw

CVE-2026-60989 Overview

CVE-2026-60989 is a high-severity vulnerability in the Oracle Advanced Collections product of Oracle E-Business Suite, specifically in the Internal Operations component. The flaw allows a low-privileged attacker with network access via HTTP to compromise Oracle Advanced Collections. Successful exploitation results in full takeover of the affected Oracle Advanced Collections instance, impacting confidentiality, integrity, and availability. Oracle disclosed the issue in the July 2026 Critical Patch Update. Supported versions 12.2.3 through 12.2.15 are affected.

Critical Impact
An authenticated attacker with low privileges can remotely take over Oracle Advanced Collections over HTTP, leading to full compromise of the module's data and operations.

Affected Products

Oracle E-Business Suite — Oracle Advanced Collections 12.2.3 through 12.2.15
Component: Internal Operations
Attack surface: HTTP-accessible Oracle E-Business Suite deployments

Technical Details for CVE-2026-60989

Vulnerability Analysis

The vulnerability resides in the Internal Operations component of Oracle Advanced Collections, a receivables management module within Oracle E-Business Suite. An attacker with a low-privileged application account can send crafted HTTP requests to reachable endpoints and compromise the module. Oracle classifies the vulnerability as easily exploitable and confirms that successful attacks result in takeover of Oracle Advanced Collections.

Because Oracle E-Business Suite frequently integrates with financial, customer, and operational data flows, a takeover of Advanced Collections can expose sensitive collections data, alter receivables records, and disrupt downstream financial processes. The scope is unchanged, meaning the impact is confined to the vulnerable component, but confidentiality, integrity, and availability are all fully impacted.

Root Cause

Oracle has not published a detailed root-cause analysis. The advisory identifies the Internal Operations component of Oracle Advanced Collections as the vulnerable surface and confirms that authentication with low privileges is sufficient to reach it over HTTP. Consult the Oracle Critical Patch Update Advisory - July 2026 for the authoritative technical description.

Attack Vector

The attack vector is network-based over HTTP. The attacker must hold a valid low-privileged account on the Oracle E-Business Suite deployment. No user interaction is required, and attack complexity is low. Any organization exposing Oracle E-Business Suite to broad user populations or partner networks materially increases exposure. No public proof-of-concept has been published, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog at the time of writing. The EPSS score is 0.479%.

No verified exploit code is publicly available. Refer to Oracle's advisory for authoritative technical details.

Detection Methods for CVE-2026-60989

Indicators of Compromise

Unexpected authenticated HTTP requests to Oracle Advanced Collections Internal Operations endpoints from low-privileged accounts.
Anomalous changes to collections, receivables, or dunning records outside normal business hours or workflows.
New or modified Oracle E-Business Suite application user sessions originating from unusual source IP addresses or user agents.

Detection Strategies

Enable and centralize Oracle E-Business Suite application and access logs, then baseline typical Advanced Collections activity per user role.
Alert on privilege-inconsistent access patterns, such as low-privileged accounts invoking Internal Operations functions or triggering administrative flows.
Correlate web server logs, database audit trails, and application logs to identify sequences consistent with account takeover of the Advanced Collections module.

Monitoring Recommendations

Monitor the Oracle E-Business Suite web tier for unusual URL patterns, parameter tampering, and elevated error rates on Advanced Collections endpoints.
Track authentication events for low-privileged EBS accounts, including failed logins followed by successful sessions and geographic anomalies.
Audit changes to Advanced Collections configuration, agents, strategies, and scoring engines, and alert on modifications made outside change-management windows.

How to Mitigate CVE-2026-60989

Immediate Actions Required

Apply the fixes from the Oracle Critical Patch Update Advisory - July 2026 to all affected Oracle E-Business Suite 12.2.3–12.2.15 environments.
Restrict network exposure of Oracle E-Business Suite so that Advanced Collections endpoints are not reachable from untrusted networks.
Review and reduce standing privileges on Oracle E-Business Suite accounts, especially those with any access to Oracle Advanced Collections.

Patch Information

Oracle addresses CVE-2026-60989 in the July 2026 Critical Patch Update. Administrators should identify affected Oracle E-Business Suite instances running versions 12.2.3 through 12.2.15 and apply the vendor-supplied patches following Oracle's documented CPU application procedures. Validate patch application in non-production environments before rolling out to production, and confirm post-patch functionality of Advanced Collections workflows.

Workarounds

If patching cannot be completed immediately, restrict HTTP access to Oracle Advanced Collections endpoints using network segmentation, VPN gating, or web application firewall rules.
Enforce strong authentication, session controls, and least privilege on all Oracle E-Business Suite accounts to reduce the pool of low-privileged accounts an attacker could abuse.
Increase logging verbosity and monitoring on the Oracle E-Business Suite web tier and database until patches are applied.

bash

# Example: restrict HTTP access to EBS Advanced Collections endpoints at the reverse proxy
# (adapt paths and CIDRs to your environment)
location /OA_HTML/ {
    allow 10.0.0.0/8;      # internal corporate range
    deny  all;
    proxy_pass http://ebs-backend;
