CVE-2026-71025 Overview
CVE-2026-71025 is a broken access control vulnerability [CWE-284] in the Endeca Application Controller component of Oracle Commerce Guided Search and Oracle Commerce Experience Manager, version 11.4.0. An unauthenticated attacker with network access via HTTP can exploit the flaw, but successful exploitation requires human interaction from a user other than the attacker. The vulnerability affects the scope of impacted components, meaning attacks can reach beyond Oracle Commerce Guided Search itself. Successful exploitation permits unauthorized read access to a subset of data and unauthorized update, insert, or delete access to some accessible data.
Critical Impact
Unauthenticated network-based exploitation with user interaction can lead to cross-scope integrity and confidentiality impact affecting additional Oracle products beyond the vulnerable component.
Affected Products
- Oracle Commerce Guided Search 11.4.0
- Oracle Commerce Experience Manager 11.4.0
- Endeca Application Controller (component)

Technical Details for CVE-2026-71025
Vulnerability Analysis
The vulnerability resides in the Endeca Application Controller, the management component that coordinates deployment, provisioning, and control of Endeca applications used by Oracle Commerce Guided Search and Experience Manager. The flaw is classified under [CWE-284] Improper Access Control. An attacker can reach the vulnerable HTTP interface without authentication, but the exploit chain requires a legitimate user to perform an action, such as visiting an attacker-controlled link or interacting with crafted content.
Because the vulnerability triggers a scope change, code executing in the vulnerable component can impact resources managed by other components or products. This behavior is typical of web-based flaws where a trusted browser context or session is coerced into performing actions across trust boundaries. The resulting impact includes limited unauthorized data modification and limited unauthorized data disclosure, without direct availability impact.
Root Cause
The root cause is improper access control within the Endeca Application Controller HTTP interface. Authorization checks are insufficient to prevent an unauthenticated request from leveraging an authenticated user's browser context to perform actions or retrieve data across the trust boundary of the application.
Attack Vector
An attacker sends crafted HTTP requests or hosts crafted web content that targets the Endeca Application Controller endpoint. The victim, typically an administrator or authenticated Oracle Commerce user, interacts with the malicious content. The victim's browser then issues requests to the vulnerable component under their session context, resulting in unauthorized reads or writes. Refer to the Oracle Security Alert August 2026 for vendor-supplied technical details.
Detection Methods for CVE-2026-71025
Indicators of Compromise
- Unexpected HTTP requests to Endeca Application Controller endpoints originating from user browsers rather than administrative workstations.
- Configuration or content changes in Oracle Commerce Guided Search / Experience Manager without a corresponding authorized change ticket.
- HTTP referer headers pointing to untrusted external domains on requests reaching the Application Controller interface.
Detection Strategies
- Enable verbose access logging on the Endeca Application Controller and correlate request timestamps with administrative session activity.
- Alert on cross-origin requests targeting Application Controller URLs, which should only be reached from trusted internal management consoles.
- Track anomalous read or write operations against Oracle Commerce content and configuration stores.
Monitoring Recommendations
- Forward web server and application logs from Oracle Commerce hosts into a centralized SIEM for correlation.
- Monitor administrator accounts for unusual browsing patterns or unexpected outbound HTTP activity coinciding with Application Controller access.
- Baseline normal Endeca Application Controller traffic and alert on deviations, particularly requests originating from user endpoints.
How to Mitigate CVE-2026-71025
Immediate Actions Required
- Apply the fix documented in the Oracle Security Alert August 2026 to all Oracle Commerce Guided Search and Experience Manager 11.4.0 deployments.
- Restrict network access to the Endeca Application Controller HTTP interface to trusted management networks only.
- Require administrators to use dedicated management workstations and browsers isolated from general web browsing.
Patch Information
Oracle addressed CVE-2026-71025 in the August 2026 Critical Patch Update. Administrators should download and deploy the patches referenced in the Oracle Security Alert August 2026 and verify installation on all Oracle Commerce 11.4.0 nodes.
Workarounds
- Place the Endeca Application Controller behind a reverse proxy that enforces origin, referer, and IP allow-list checks.
- Disable or block direct browser access to Application Controller endpoints from user network segments.
- Educate administrators to avoid clicking untrusted links while authenticated to Oracle Commerce management consoles.
# Example: restrict Endeca Application Controller access to a management subnet via iptables
iptables -A INPUT -p tcp --dport 8006 -s 10.10.50.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 8006 -j DROP
