CVE-2026-61186: Oracle Agile Engineering Data DOS Flaw

CVE-2026-61186 Overview

CVE-2026-61186 affects the Install component of Oracle Agile Engineering Data Management, part of the Oracle Supply Chain product family. The vulnerability lets an unauthenticated attacker with network access over HTTP compromise the application. Successful exploitation grants unauthorized creation, deletion, or modification of critical data, partial read access to application data, and the ability to trigger a hang or repeatable crash resulting in complete denial of service. Oracle disclosed the issue in the Oracle Security Alert July 2026.

Critical Impact
An unauthenticated network attacker can achieve high-impact write access, partial data disclosure, and full denial of service against Oracle Agile Engineering Data Management 6.2.1.

Affected Products

Oracle Agile Engineering Data Management 6.2.1
Oracle Supply Chain product family (Install component)
Deployments exposing the application over HTTP

Technical Details for CVE-2026-61186

Vulnerability Analysis

The flaw resides in the Install component of Oracle Agile Engineering Data Management version 6.2.1. Oracle categorizes the vulnerability as easily exploitable over the network without authentication or user interaction. An attacker sending crafted HTTP requests can achieve high-impact integrity and availability effects along with limited confidentiality exposure.

The combination of unauthenticated network reachability and high integrity impact suggests weaknesses in request handling, access control, or input validation within the Install component. Impact spans all data accessible to the application, meaning an attacker can tamper with engineering records, bill-of-materials data, and product lifecycle content processed by the platform.

Root Cause

Oracle has not published a detailed technical breakdown. Based on the advisory language and scope, the root cause is an authentication or authorization gap in an HTTP-facing interface exposed by the Install component. The absence of privilege requirements combined with unchanged scope indicates the vulnerable code path executes with application-level trust before verifying the caller.

Attack Vector

The attack vector is network-based over HTTP. An attacker only needs reachability to the Oracle Agile Engineering Data Management HTTP listener. No credentials, tokens, or user interaction are required. Because the Install component often runs during deployment and administrative operations, exposure of these endpoints to untrusted networks materially increases risk.

Refer to the Oracle Security Alert July 2026 for vendor-provided technical context.

Detection Methods for CVE-2026-61186

Indicators of Compromise

Unauthenticated HTTP requests to Oracle Agile Engineering Data Management Install component endpoints from unexpected source addresses
Unexpected creation, deletion, or modification of records in Agile EDM databases without corresponding authenticated user sessions
Application-tier crashes, hangs, or restart loops correlated with inbound HTTP traffic bursts
New or modified administrative artifacts appearing outside change-management windows

Detection Strategies

Enable verbose HTTP access logging on the Agile EDM front-end and alert on requests to Install component paths from non-administrative subnets
Correlate application audit logs with web-tier logs to identify data changes that lack an authenticated user context
Baseline normal request patterns to the Install component and flag deviations in method, path, or payload size

Monitoring Recommendations

Forward Oracle Agile EDM web, application, and database logs into a central analytics platform for cross-source correlation
Monitor process health and service restart events on Agile EDM hosts to catch denial-of-service attempts
Track outbound connections from Agile EDM hosts to detect follow-on activity after a successful compromise

How to Mitigate CVE-2026-61186

Immediate Actions Required

Apply the fixes distributed in the Oracle Critical Patch Update / Security Alert of July 2026 to all Oracle Agile Engineering Data Management 6.2.1 deployments
Restrict network access to the Agile EDM HTTP interface so only trusted administrative networks can reach it
Inventory all Agile EDM instances, including non-production and disaster-recovery copies, and confirm patch status on each
Review recent database and application audit records for signs of unauthorized modification

Patch Information

Oracle addressed CVE-2026-61186 in the July 2026 Security Alert cycle. Administrators should download and apply the corresponding patch for Oracle Agile Engineering Data Management 6.2.1 as documented in the Oracle Security Alert July 2026. Oracle recommends applying Critical Patch Update fixes without delay.

Workarounds

Place the Agile EDM HTTP endpoint behind a reverse proxy or web application firewall that enforces source-address allowlisting
Disable or firewall-block Install component endpoints when they are not actively required for deployment tasks
Require VPN or zero-trust network access for all administrative interactions with Agile EDM until patches are deployed

bash

# Example: restrict inbound access to the Agile EDM HTTP listener to a trusted admin subnet
iptables -A INPUT -p tcp --dport 8080 -s 10.10.20.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 8080 -j DROP
