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 · unedited
Vulnerability in the Oracle WebCenter Sites product of Oracle Fusion Middleware (component: WebCenter Sites). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.0.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle WebCenter Sites. While the vulnerability is in Oracle WebCenter Sites, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in takeover of Oracle WebCenter Sites. CVSS 3.1 Base Score 10.0 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/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 · moderate confidence

Unauthenticated remote attacker with network access via HTTP can compromise Oracle WebCenter Sites versions 12.2.1.4.0 and 14.1.2.0.0, achieving complete takeover with full confidentiality, integrity, and availability impacts. The vulnerability enables arbitrary code execution or authentication bypass, with potential scope expansion affecting additional Oracle products.

MitigationApply Oracle Critical Patch Update for WebCenter Sites (CPU) addressing this vulnerability, or upgrade to patched versions if available. Restrict network exposure of WebCenter Sites interfaces to trusted networks until patch is deployed.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Verify Oracle WebCenter Sites is installed
    Check for WebCenter Sites installation directories (commonly under $ORACLE_HOME or C:\Oracle\WebCenter\Sites) or look for the 'Oracle WebCenter Sites' service running on the system.
    Affected if The product is not installed or no WebCenter Sites service is found.
  2. Determine the installed WebCenter Sites version
    Access the WebCenter Sites Administration interface About page (typically at /Sites/Admin or /servlet/Admin) or check version files in the installation directory such as version.txt or the product manifest. Alternatively, check Oracle inventory files if available.
    Affected if The version displayed is exactly 12.2.1.4.0 or 14.1.2.0.0.
  3. Confirm HTTP interface network exposure
    Attempt to access the WebCenter Sites HTTP endpoints from an untrusted network location using curl or a browser (common paths include /Sites/Admin, /servlet/ContentServer, /openam or similar). Verify whether the interface binds to 0.0.0.0 or a public IP versus localhost only.
    Affected if The HTTP interface is accessible from untrusted networks or exposes standard WebCenter Sites endpoints.
  4. Check for unauthenticated endpoint accessibility
    Attempt to reach unauthenticated WebCenter Sites endpoints (such as REST APIs, ContentServer servlets, or login pages) without providing credentials to confirm if authentication is required or can be bypassed.
    Affected if Unauthenticated access to sensitive endpoints is possible without redirection to a login page.

If Oracle WebCenter Sites is running version 12.2.1.4.0 or 14.1.2.0.0 and its HTTP interface is network-accessible, the environment is affected by CVE-2026-46800 and vulnerable to unauthenticated remote compromise.
