CVE-2026-46765
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedVulnerability in the Oracle WebCenter Portal product of Oracle Fusion Middleware (component: Composer). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.0.0. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle WebCenter Portal. While the vulnerability is in Oracle WebCenter Portal, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in takeover of Oracle WebCenter Portal. CVSS 3.1 Base Score 9.9 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H).
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA critical vulnerability in the Composer component of Oracle WebCenter Portal (versions 12.2.1.4.0 and 14.1.2.0.0) allows a low-privileged attacker with network access via HTTP to achieve complete takeover of the portal, with potential scope expansion to impact additional products.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Oracle WebCenter Portal installationLocate WebCenter Portal installation directories (typically under $ORACLE_HOME in Oracle Fusion Middleware) or check for running WebCenter Portal services/processes using commands like 'ps aux | grep webcenter' or by reviewing application server deployments.Affected if WebCenter Portal is not installed on the system.
-
Identify installed WebCenter Portal versionCheck version files such as $ORACLE_HOME/VERSION.txt, the Oracle Enterprise Manager console, or the WebCenter Portal admin interface (typically at /webcenter/faces/admin). Compare the installed version to 12.2.1.4.0 or 14.1.2.0.0.Affected if The installed version is exactly 12.2.1.4.0 or 14.1.2.0.0.
-
Confirm Composer component is configuredAccess the WebCenter Portal administration console and navigate to the Composer settings, or examine the Oracle Enterprise Manager Fusion Middleware Control for Composer component status. Check for composer-related web application deployments in the WebCenter domain.Affected if Composer component is not present or not configured in the WebCenter Portal deployment.
-
Check network accessibility of Composer endpointTest HTTP/HTTPS access to the Composer application URL (typically /webcenter/faces/composer or similar composer-related endpoints) from within the network using curl or a browser. Review network firewall rules and load balancer configurations exposing this component.Affected if The Composer component is exposed to network access without authentication restrictions.
You are affected if Oracle WebCenter Portal versions 12.2.1.4.0 or 14.1.2.0.0 are installed with the Composer component enabled and network-accessible via HTTP.
