CVE-2026-60492 Overview
CVE-2026-60492 affects Oracle JD Edwards EnterpriseOne HCM Foundation version 9.2, specifically the OW HR PR Foundation component. The vulnerability allows a low-privileged attacker with network access via HTTP to disrupt the application. Successful exploitation can produce a hang or repeatable crash that results in a complete denial of service. The same flaw also grants unauthorized read access to a subset of data handled by JD Edwards EnterpriseOne HCM Foundation. Oracle disclosed the issue in the July 2026 Critical Patch Update.
Critical Impact
A low-privileged remote attacker can trigger a full denial of service on JD Edwards EnterpriseOne HCM Foundation and read a subset of application data over HTTP.
Affected Products
- Oracle JD Edwards EnterpriseOne HCM Foundation 9.2
- Component: OW HR PR Foundation
- Deployments exposing JD Edwards HTTP interfaces to authenticated users

Technical Details for CVE-2026-60492
Vulnerability Analysis
The vulnerability resides in the OW HR PR Foundation component of Oracle JD Edwards EnterpriseOne HCM Foundation 9.2. The flaw is reachable over the network through HTTP and requires only low privileges to exploit. No user interaction is required, and the attack complexity is low.
Exploitation produces two distinct outcomes. First, the attacker can force the HCM Foundation service into a hang state or trigger a repeatable crash, halting HR and payroll processing. Second, the same request path exposes a subset of application data to unauthorized read access. The confidentiality impact is limited, while the availability impact is high. Oracle categorizes the issue in the July 2026 Critical Patch Update advisory.
Root Cause
Oracle has not published detailed root-cause information for CVE-2026-60492. The advisory characterizes the issue as a denial-of-service condition combined with partial information disclosure in the HCM Foundation component. Refer to the Oracle Security Alert - July 2026 for authoritative details.
Attack Vector
The attack vector is network-based and delivered over HTTP against the JD Edwards EnterpriseOne HCM Foundation web-accessible endpoints. The attacker must hold a valid low-privileged account within the application. No user interaction is required, and the scope is unchanged. The confidentiality impact is low, integrity impact is none, and availability impact is high.
No public proof-of-concept or exploitation in the wild has been reported. The EPSS probability is 0.365% with a percentile of 28.99, indicating limited near-term exploitation likelihood based on current telemetry.
Detection Methods for CVE-2026-60492
Indicators of Compromise
- Unexpected hangs, timeouts, or repeatable crashes of JD Edwards EnterpriseOne HCM Foundation services on version 9.2.
- Authenticated low-privileged sessions issuing repeated or malformed HTTP requests to OW HR PR Foundation endpoints.
- Application or web server logs showing unusual response patterns from HCM Foundation URLs, followed by service restarts.
Detection Strategies
- Correlate authentication logs with HTTP access logs to identify low-privileged accounts making anomalous request volumes to HCM Foundation URLs.
- Alert on JD Edwards service crashes or process restarts in Windows Event Log or Linux syslog on hosts running HCM Foundation 9.2.
- Baseline normal request patterns for OW HR PR Foundation endpoints and flag statistical deviations.
Monitoring Recommendations
- Forward JD Edwards EnterpriseOne web server logs, application server logs, and OS logs to a centralized SIEM for correlation.
- Monitor availability metrics (response latency, error rates, worker thread saturation) on HCM Foundation endpoints.
- Track authenticated session activity against sensitive HCM data reads to identify unauthorized access patterns.
How to Mitigate CVE-2026-60492
Immediate Actions Required
- Apply the fixes from the Oracle Critical Patch Update - July 2026 to all JD Edwards EnterpriseOne HCM Foundation 9.2 instances.
- Inventory all internet-facing and intranet-facing JD Edwards deployments and prioritize patching those exposed to broad user populations.
- Audit accounts with access to HCM Foundation and remove unnecessary low-privileged accounts that could be leveraged for exploitation.
Patch Information
Oracle addressed CVE-2026-60492 in the July 2026 Critical Patch Update. Administrators should download the applicable patch for JD Edwards EnterpriseOne HCM Foundation 9.2 from My Oracle Support and apply it following Oracle's documented patching procedures. Refer to the Oracle Security Alert - July 2026 for the full patch matrix.
Workarounds
- Restrict network access to JD Edwards EnterpriseOne HCM Foundation HTTP endpoints using firewall rules, VPN gating, or reverse-proxy allowlists until patching completes.
- Enforce least-privilege on JD Edwards application accounts and disable inactive users to reduce the pool of accounts an attacker could abuse.
- Deploy a web application firewall in front of JD Edwards to rate-limit and inspect requests targeting HCM Foundation URLs.
# Example: restrict HTTP access to JD Edwards HCM Foundation to trusted subnets
iptables -A INPUT -p tcp --dport 443 -s 10.10.0.0/16 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP
