CVE-2026-61153 Overview
CVE-2026-61153 is a critical vulnerability affecting Oracle Commerce Guided Search and Oracle Commerce Experience Manager version 11.4.0. The flaw resides in the Experience Manager component and allows an unauthenticated remote attacker to compromise the product over HTTP. Successful exploitation grants unauthorized read, create, delete, and modify access to critical data across the application.
Oracle published the advisory as part of the Oracle Security Alert July 2026. The vulnerability is easily exploitable and requires no user interaction, elevating its risk profile for internet-facing deployments.
Critical Impact
An unauthenticated network attacker can fully compromise the confidentiality and integrity of all data accessible to Oracle Commerce Guided Search / Experience Manager.

Technical Details for CVE-2026-61153
Vulnerability Analysis
The vulnerability exists in the Experience Manager component of Oracle Commerce Guided Search / Oracle Commerce Experience Manager 11.4.0. An attacker with network access via HTTP can exploit the flaw without authentication and without user interaction. Successful attacks result in unauthorized creation, deletion, or modification of critical data, as well as unauthorized read access to all accessible data.
Because the attack vector is network-based and requires low complexity, exposed Experience Manager instances are directly reachable and exploitable. The EPSS score is 0.398% as of 2026-07-23, indicating current exploitation likelihood remains low, though this can change once technical details or proof-of-concept code emerge.
Root Cause
Oracle has not published detailed technical root-cause information. Based on the impact profile — unauthenticated HTTP access producing full read and write control over application data — the flaw is consistent with a broken access control or authentication bypass issue within the Experience Manager component. Refer to the Oracle Security Alert July 2026 for authoritative details.
Attack Vector
An attacker sends crafted HTTP requests to an exposed Oracle Commerce Experience Manager endpoint. Because no authentication is required, exploitation can be automated at scale against internet-facing instances. Once access is obtained, the attacker can read, modify, or delete Experience Manager data, which typically includes merchandising rules, catalog content, and customer-facing storefront configurations.
No verified public exploit code is available at the time of publication. See the vendor advisory for technical references.
Detection Methods for CVE-2026-61153
Indicators of Compromise
- Unauthenticated HTTP or HTTPS requests to Experience Manager administrative or content endpoints from external sources.
- Unexpected creation, modification, or deletion of merchandising rules, cartridges, or catalog content in Experience Manager audit logs.
- Anomalous outbound connections from Oracle Commerce application servers following inbound HTTP activity.
Detection Strategies
- Inspect web server and application logs for requests to Experience Manager endpoints that lack valid session or authentication headers.
- Correlate content-change events in Experience Manager with the originating request source and user identity.
- Baseline normal administrative traffic patterns and alert on off-hours or high-volume content mutations.
Monitoring Recommendations
- Forward Oracle Commerce application and web tier logs to a centralized SIEM for retention and correlation.
- Enable alerting on HTTP 200 responses to sensitive Experience Manager paths from unauthenticated sessions.
- Monitor for enumeration behavior such as sequential path probing against /ifcr, /experience-manager, or related endpoints.
How to Mitigate CVE-2026-61153
Immediate Actions Required
- Apply the fixes contained in the Oracle Security Alert July 2026 to all Oracle Commerce Guided Search / Experience Manager 11.4.0 deployments.
- Restrict network access to Experience Manager administrative interfaces so they are not reachable from untrusted networks.
- Review Experience Manager audit trails for unauthorized content changes since exposure began.
Patch Information
Oracle addressed CVE-2026-61153 in the July 2026 Critical Patch Update cycle. Administrators should download and apply the patch bundle referenced in the Oracle Security Alert for version 11.4.0. Validate the patch installation in a staging environment before promoting to production.
Workarounds
- Place Experience Manager behind a reverse proxy or web application firewall that enforces authentication on all administrative paths.
- Apply network access control lists to permit management traffic only from trusted administrative subnets or VPN ranges.
- Disable or firewall off any Experience Manager endpoints not required for production storefront operations until the patch is applied.
