CVE-2026-60552 Overview
CVE-2026-60552 is a critical vulnerability in Oracle WebCenter Sites, a component of Oracle Fusion Middleware. The flaw affects supported versions 12.2.1.4.0 and 14.1.2.0.0. A low-privileged attacker with network access via HTTP can exploit the issue without user interaction. Successful exploitation results in complete takeover of Oracle WebCenter Sites. The vulnerability carries a scope change, meaning attacks may impact additional products beyond the vulnerable component. Oracle disclosed the issue in the July 2026 Critical Patch Update.
Critical Impact
Attackers with low-privilege network access can fully compromise Oracle WebCenter Sites, with attacks extending to additional products through scope change.
Affected Products
- Oracle WebCenter Sites 12.2.1.4.0
- Oracle WebCenter Sites 14.1.2.0.0
- Oracle Fusion Middleware deployments hosting the affected WebCenter Sites component

Technical Details for CVE-2026-60552
Vulnerability Analysis
The vulnerability resides in the WebCenter Sites component of Oracle Fusion Middleware. An authenticated attacker holding only low privileges can send crafted HTTP requests to exploit the flaw. The attack complexity is low and no user interaction is required. Because the vulnerability introduces a scope change, exploitation can affect resources managed outside the security authority of WebCenter Sites. Successful exploitation results in high impact to confidentiality, integrity, and availability, effectively enabling takeover of the product.
The EPSS score is 0.447% with a percentile of 36.433, based on data from 2026-07-23. Oracle has not published detailed root-cause information beyond the advisory summary.
Root Cause
Oracle's advisory identifies the WebCenter Sites component as the source of the flaw but does not disclose the underlying technical defect. The combination of network attack vector, low privilege requirement, and scope change suggests a flaw in request handling or access enforcement that allows privileged operations to reach components outside the trust boundary of the calling user.
Attack Vector
An attacker requires network reachability to the WebCenter Sites HTTP interface and any low-privileged authenticated session. The attacker then issues HTTP requests to the vulnerable component to achieve takeover. No local access or user interaction is required. Deployments exposing WebCenter Sites to untrusted networks face the greatest exposure. See the Oracle Security Alert July 2026 for vendor guidance.
No public proof-of-concept exploit is available at time of publication.
Detection Methods for CVE-2026-60552
Indicators of Compromise
- Unexpected HTTP requests to Oracle WebCenter Sites endpoints originating from low-privilege user sessions
- Creation of new administrative accounts or roles inside WebCenter Sites without corresponding change tickets
- Unusual outbound connections initiated by the WebCenter Sites JVM process
- Modifications to site templates, assets, or configuration files outside scheduled deployment windows
Detection Strategies
- Enable verbose HTTP access logging on the WebCenter Sites application server and correlate anomalous request patterns tied to low-privileged accounts
- Monitor authentication logs for session escalation events or access to administrative URIs by non-admin users
- Baseline expected traffic to WebCenter Sites administrative paths and alert on deviations
Monitoring Recommendations
- Forward Oracle Fusion Middleware, WebLogic, and web server logs to a centralized analytics platform for correlation
- Track file integrity for WebCenter Sites configuration and deployment directories
- Alert on process spawning by the application server JVM, which is a common post-exploitation indicator for scope-changing web application flaws
How to Mitigate CVE-2026-60552
Immediate Actions Required
- Apply the fixes distributed in the Oracle Security Alert July 2026 to affected WebCenter Sites deployments
- Inventory all Oracle Fusion Middleware installations to identify instances running 12.2.1.4.0 or 14.1.2.0.0
- Restrict network access to WebCenter Sites administrative interfaces to trusted management networks until patches are deployed
- Review recent authentication and administrative activity for signs of prior exploitation
Patch Information
Oracle addressed CVE-2026-60552 in the July 2026 Critical Patch Update. Administrators should download and apply the WebCenter Sites patches referenced in the Oracle Security Alert July 2026. Oracle recommends applying Critical Patch Update fixes without delay.
Workarounds
- Place WebCenter Sites behind a web application firewall with rules restricting access to administrative endpoints
- Enforce network segmentation so only trusted upstream proxies reach the WebCenter Sites HTTP listener
- Rotate credentials for low-privileged accounts and enforce strong authentication to reduce the pool of accounts capable of initiating exploitation
- Disable or remove unused low-privilege application accounts pending patch deployment
# Example: restrict WebCenter Sites HTTP listener to trusted management network via iptables
iptables -A INPUT -p tcp --dport 7003 -s 10.10.20.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 7003 -j DROP
