CVE-2026-60700: Oracle Universal Work Queue Auth Bypass

CVE-2026-60700 Overview

CVE-2026-60700 is a high-severity vulnerability in the Oracle Universal Work Queue (UWQ) component of Oracle E-Business Suite. The flaw resides in the UWQ Server Issues subcomponent and affects supported versions 12.2.3 through 12.2.15. An unauthenticated remote attacker with network access via HTTP can exploit the vulnerability, but successful attacks require interaction from a user other than the attacker. Exploitation can lead to unauthorized creation, deletion, or modification of critical data, as well as unauthorized access to all UWQ-accessible data. Oracle addressed the issue in the July 2026 Critical Patch Update.

Critical Impact
Unauthenticated network attackers can compromise the confidentiality and integrity of all data accessible through Oracle Universal Work Queue when a legitimate user is lured into interaction.

Affected Products

Oracle E-Business Suite — Oracle Universal Work Queue 12.2.3 through 12.2.15
Component: UWQ Server Issues

Technical Details for CVE-2026-60700

Vulnerability Analysis

The vulnerability affects the server-side handling of requests within the Oracle Universal Work Queue component of Oracle E-Business Suite. UWQ is used to distribute and manage work items across users of E-Business Suite modules, so it processes data from multiple business contexts. An unauthenticated attacker reaches the vulnerable code path over HTTP without requiring valid credentials. The attack succeeds only when a legitimate user interacts with attacker-supplied content, indicating a client-mediated exploitation path such as a crafted link or malicious page. Once triggered, the attacker gains read and write access to data that the interacting user can access through UWQ.

Root Cause

Oracle has not publicly disclosed the underlying defect class. Based on the advisory metadata, the flaw is reachable over HTTP without authentication and depends on user interaction to complete the exploit chain. This pattern is consistent with server-side request handling flaws that are triggered through victim-initiated navigation or content rendering. Refer to the Oracle Security Alert July 2026 for authoritative technical detail.

Attack Vector

The attack originates from the network. The attacker crafts a request or resource that targets a vulnerable UWQ endpoint on an exposed E-Business Suite deployment. A user other than the attacker must perform an action, such as clicking a link or loading an attacker-influenced page, for the exploit to succeed. The scope remains unchanged, and impact is limited to confidentiality and integrity of UWQ-accessible data. Availability is not affected according to the CVSS vector published with the advisory.

No verified public exploit or proof-of-concept code is available at this time. See the Oracle Security Alert July 2026 for vendor-provided technical detail.

Detection Methods for CVE-2026-60700

Indicators of Compromise

Unexpected HTTP requests to Oracle Universal Work Queue endpoints from external or untrusted sources.
Unauthenticated access attempts to UWQ URLs followed by authenticated user activity from the same session context.
Anomalous creation, modification, or deletion events in UWQ-managed work items outside normal business workflows.

Detection Strategies

Inspect web server and application logs on E-Business Suite tiers for HTTP requests targeting UWQ handlers with unusual parameters or referrers.
Correlate user interaction events, such as email link clicks or web navigation, with subsequent UWQ data changes to identify user-mediated exploitation chains.
Baseline normal UWQ traffic patterns and alert on request spikes, off-hours access, or requests originating from geographies outside the user population.

Monitoring Recommendations

Forward Oracle HTTP Server, WebLogic, and E-Business Suite audit logs to a centralized analytics platform for cross-source correlation.
Enable database-level auditing on UWQ tables to record unauthorized create, update, and delete operations.
Alert on failed and successful authentication anomalies that follow HTTP interaction with UWQ endpoints.

How to Mitigate CVE-2026-60700

Immediate Actions Required

Apply the Oracle July 2026 Critical Patch Update to all Oracle E-Business Suite instances running Universal Work Queue versions 12.2.3 through 12.2.15.
Inventory internet-facing E-Business Suite deployments and prioritize patching those exposed to untrusted networks.
Warn end users about phishing and link-based lures targeting E-Business Suite users, since exploitation requires user interaction.

Patch Information

Oracle released fixes as part of the July 2026 Critical Patch Update. Consult the Oracle Security Alert July 2026 for the specific patch identifiers, prerequisites, and application instructions for each supported version between 12.2.3 and 12.2.15.

Workarounds

Restrict access to Oracle Universal Work Queue endpoints to trusted internal networks using firewall or reverse proxy rules until patches are applied.
Enforce web application firewall policies that filter anomalous requests to UWQ URIs and inspect referrers on user-initiated navigation.
Reduce browser-based exposure by encouraging users to log out of E-Business Suite sessions when not in use and to avoid clicking untrusted links while authenticated.

bash

# Example: restrict UWQ endpoint exposure at the reverse proxy layer
# Replace <trusted_cidr> with your internal network range
location /OA_HTML/uwq {
    allow <trusted_cidr>;
    deny  all;
    proxy_pass http://ebs-backend;
}
