CVE-2026-61127 Overview
CVE-2026-61127 is a high-severity vulnerability in the Oracle Communications Service Catalog and Design product, specifically within the Solution Designer component. The flaw affects supported versions 8.0.0.7.0 through 8.3.0.2.0. A low-privileged attacker with network access via HTTP can exploit this vulnerability to fully compromise the application. Successful exploitation results in complete takeover of Oracle Communications Service Catalog and Design, impacting confidentiality, integrity, and availability. Oracle disclosed this issue as part of the Oracle Security Alert July 2026 advisory cycle.
Critical Impact

Technical Details for CVE-2026-61127
Vulnerability Analysis
CVE-2026-61127 resides in the Solution Designer component of Oracle Communications Service Catalog and Design. The vulnerability is remotely exploitable over HTTP with low attack complexity and requires only low privileges. No user interaction is needed. Successful exploitation allows an attacker to escape the intended trust boundary of an authenticated session and gain full control of the affected application. The impact scope includes read access to sensitive configuration and subscriber data, modification of service catalog objects, and disruption of catalog operations.
Root Cause
Oracle has not published detailed root-cause information for CVE-2026-61127. The advisory characterizes the issue as easily exploitable through the network-facing HTTP interface of the Solution Designer component. The combination of low privilege requirement and unchanged scope with high impacts across confidentiality, integrity, and availability indicates a flaw that grants an authenticated user access to functionality or data beyond their authorization level within the application context.
Attack Vector
The attack vector is network-based. An attacker who holds any valid low-privileged account on the Solution Designer application can send crafted HTTP requests to a vulnerable endpoint. Because no user interaction is required and complexity is low, the flaw is well-suited to automation. Attackers reaching the HTTP service from internal networks, VPN tunnels, or exposed management interfaces can chain this vulnerability with lateral movement to take over the catalog and its downstream service-provisioning workflows.
Refer to the Oracle Security Alert July 2026 for vendor-supplied technical details.
Detection Methods for CVE-2026-61127
Indicators of Compromise
- Unexpected HTTP requests from low-privileged accounts targeting Solution Designer administrative or design endpoints.
- Creation, modification, or deletion of catalog design objects outside of change-approved windows.
- New or modified user accounts, roles, or privilege assignments within the Service Catalog and Design application.
- Outbound connections from the Service Catalog and Design host to unfamiliar destinations following authenticated sessions.
Detection Strategies
- Enable and forward Oracle Communications Service Catalog and Design application and web-tier audit logs to a centralized log platform.
- Correlate authentication events with subsequent administrative HTTP actions to identify privilege abuse by low-privileged accounts.
- Baseline normal Solution Designer request patterns per user role and alert on deviations such as unusual endpoint access or high request volumes.
Monitoring Recommendations
- Monitor web server access logs for anomalous URI patterns, HTTP methods, or parameters against Solution Designer endpoints.
- Track configuration and catalog schema changes for out-of-band modifications and unauthorized approvals.
- Alert on failed-to-successful login transitions followed by rapid privileged operations from the same session.
How to Mitigate CVE-2026-61127
Immediate Actions Required
- Apply the fixes from the Oracle Security Alert July 2026 to all affected Service Catalog and Design instances.
- Inventory deployments running versions 8.0.0.7.0 through 8.3.0.2.0 and prioritize internet-adjacent or shared-tenant systems.
- Rotate credentials and review role assignments for all Solution Designer users, focusing on low-privileged accounts.
- Review audit logs for signs of exploitation since exposure of the affected versions.
Patch Information
Oracle addressed CVE-2026-61127 in the July 2026 Critical Patch Update cycle. Administrators should consult the Oracle Security Alert July 2026 for the specific patch bundle applicable to their supported version and follow the documented upgrade or patch application procedure.
Workarounds
- Restrict network access to the Solution Designer HTTP interface using firewall rules or reverse-proxy allowlists limited to trusted management networks.
- Enforce strong authentication and reduce the number of accounts with any level of Solution Designer access until patches are applied.
- Place the application behind a web application firewall configured to log and rate-limit requests to Solution Designer endpoints.
- Increase audit log verbosity and retention to support post-patch forensic review.
