CVE-2026-46895: Oracle ECC Framework Auth Bypass Flaw

CVE-2026-46895 Overview

CVE-2026-46895 is a critical vulnerability in the Oracle Enterprise Command Center Framework, a component of Oracle E-Business Suite. The flaw affects supported versions V15 and V16 and resides in the product's Core component. A low-privileged attacker with network access over HTTP can exploit the vulnerability without user interaction. Successful exploitation results in complete takeover of the Oracle Enterprise Command Center Framework. The vulnerability carries a scope change, meaning attacks can significantly impact additional products beyond the vulnerable component. Oracle published the security alert addressing this issue in June 2026.

Critical Impact
Authenticated attackers can take over the Oracle Enterprise Command Center Framework over the network and pivot to affect additional Oracle E-Business Suite components through scope change.

Affected Products

Oracle Enterprise Command Center Framework V15
Oracle Enterprise Command Center Framework V16
Oracle E-Business Suite deployments using the affected framework versions

Technical Details for CVE-2026-46895

Vulnerability Analysis

The vulnerability is classified under [CWE-269] Improper Privilege Management. An authenticated user with minimal privileges can escalate access and compromise the entire Oracle Enterprise Command Center Framework instance. Because the CVSS scope is changed, the impact extends beyond the vulnerable component to other Oracle E-Business Suite products that integrate with the framework.

Exploitation requires only network access via HTTP and no user interaction. Attack complexity is low, and the impact spans confidentiality, integrity, and availability. The EPSS probability is approximately 0.402% with a percentile near the 32nd, indicating limited public exploitation activity at the time of disclosure.

The framework powers analytical dashboards across Oracle E-Business Suite modules. Compromise of the framework can expose financial, HR, supply chain, and procurement data depending on the deployment.

Root Cause

Oracle's advisory attributes the issue to the Core component of the Enterprise Command Center Framework. Improper privilege management allows actions reserved for higher-privileged roles to be performed by users holding low-privileged accounts. Specific code-level details are not disclosed in Oracle's security alert.

Attack Vector

The attack vector is network-based over HTTP. An attacker authenticates with a low-privileged account to the Oracle E-Business Suite environment, then issues crafted requests to the Enterprise Command Center Framework endpoints. The scope change indicates that the framework executes operations under elevated authority, allowing the attacker to influence resources controlled by other security authorities. Oracle has not released a public proof-of-concept, and no exploitation in the wild has been confirmed.

Technical exploitation details are not publicly available. Refer to the Oracle Security Alert for vendor-provided technical context.

Detection Methods for CVE-2026-46895

Indicators of Compromise

Unexpected HTTP requests from low-privileged user sessions targeting Enterprise Command Center Framework URLs under /OA_HTML/ or ecc/ paths
New or modified Enterprise Command Center dashboards, data sets, or component registrations created by non-administrative accounts
Outbound connections or data queries from the framework process to systems not part of normal E-Business Suite operations
Application server log entries showing authorization warnings followed by successful privileged operations

Detection Strategies

Audit Oracle E-Business Suite FND_LOG_MESSAGES and Enterprise Command Center audit tables for privilege changes initiated by accounts without administrative roles
Monitor middle-tier web server access logs for anomalous POST requests to Enterprise Command Center endpoints from low-privileged session identifiers
Correlate authentication events with subsequent administrative actions to identify horizontal or vertical privilege escalation patterns

Monitoring Recommendations

Forward Oracle E-Business Suite application, database, and middle-tier logs to a centralized SIEM with retention sufficient for incident investigation
Establish baselines for normal Enterprise Command Center usage per role and alert on deviations
Track changes to responsibility assignments and role grants within Oracle E-Business Suite user management

How to Mitigate CVE-2026-46895

Immediate Actions Required

Apply the patches referenced in the Oracle June 2026 Critical Security Patch Update to all Enterprise Command Center Framework V15 and V16 instances
Inventory all Oracle E-Business Suite environments to confirm which deployments include the Enterprise Command Center Framework
Review accounts with access to the framework and remove unnecessary low-privileged user accounts that could be abused for exploitation
Restrict network access to Oracle E-Business Suite HTTP endpoints to trusted internal networks until patching is complete

Patch Information

Oracle addressed CVE-2026-46895 in the June 2026 Critical Security Patch Update. Administrators should consult the Oracle Security Alert for the specific patch identifiers applicable to their Enterprise Command Center Framework version and apply them through standard Oracle E-Business Suite patching procedures.

Workarounds

Limit Enterprise Command Center Framework access to administrative networks using web application firewall or reverse proxy access control lists
Disable unused Enterprise Command Center dashboards and components to reduce the attack surface
Enforce multi-factor authentication on all Oracle E-Business Suite accounts to raise the bar for attackers attempting to obtain the low-privileged access required for exploitation
Increase logging verbosity on the framework's middle tier and database schemas to support rapid detection while patches are deployed
