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. Confirm Oracle E-Business Suite installation
    Locate the E-Business Suite installation directory (typically $ORACLE_HOME) and verify the presence of Oracle Applications. Check for the presence of the Configurator component directory under $ORACLE_HOME/forms/java or $ORACLE_HOME/oc4j.
    Affected if Oracle E-Business Suite with Configurator component is not installed or not in use.
  2. Determine Oracle Configurator version
    Use the Oracle Application Manager (OAM) or run the command 'adident Header $ORACLE_HOME/forms/java/oracle/apps/fnd/czui/ConfiguratorMain.class' if available. Alternatively, query the FND_PRODUCT_INSTALLATIONS table via SQL if database access is available: SELECT product_version FROM fnd_product_installations WHERE product_name LIKE '%Configurator%';
    Affected if The installed version falls within 12.2.3 through 12.2.15.
  3. Verify Configurator UI HTTP accessibility
    Check if the Configurator UI servlet is exposed by accessing the URL pattern typically used (such as /servlets/Configurator or /OA_HTML/Configurator) via an unauthenticated HTTP request to the E-Business Suite web server. Review the Oracle HTTP Server configuration files (httpd.conf or oracle_apache.conf) for any RewriteRules or Alias directives exposing the Configurator paths.
    Affected if The Configurator UI endpoint is reachable via HTTP/HTTPS without authentication.
  4. Review web entry point security
    Examine the Oracle E-Business Suite function security configuration for the Configurator functions. Query SELECT function_name, web_html_name FROM fnd_form_functions WHERE web_html_name LIKE '%configurator%' OR function_name LIKE '%configurator%'; to identify protected functions. Check if guest user access or public shortcuts are enabled for these functions.
    Affected if The Configurator functions are accessible to unauthenticated or low-privileged users.

The environment is affected if Oracle E-Business Suite 12.2.3-12.2.15 with the Configurator component is installed and the Configurator UI is accessible via unauthenticated HTTP requests.

Upgrade available Upgrade to a release after 12.2.15
Interim mitigation

Apply the relevant Oracle Critical Patch Update (CPU) for CVE-2026-21972 to the Oracle Configurator component, or apply the specific patch for this vulnerability from Oracle Support.

Recommended fix Moderate confidence

Oracle Configurator 12.2.16 or later (next available release after 12.2.15)

  1. 1. Identify current Oracle Configurator version by navigating to Oracle Application Manager > Oracle Configurator or checking the about page.
  2. 2. Confirm the version falls within the affected range (12.2.3-12.2.15).
  3. 3. Subscribe to Oracle Critical Patch Updates to receive future security patches: https://www.oracle.com/security-alerts/
  4. 4. Apply the latest Oracle E-Business Suite Fusion Middleware plug-in updates for Configurator.
  5. 5. After upgrade, verify the Configurator UI is accessible and functioning normally.
Caveat Verify compatibility of custom Configurator UI extensions with the new release; test thoroughly in a non-production environment before deploying
