Project: Next.js [1]
Date: 2025-December-03
Security risk: *Critical* 16 ∕ 25
AC:Basic/A:None/CI:Some/II:Some/E:Theoretical/TD:All [2]
Vulnerability: Access bypass

Affected versions: <1.6.4 || >=2.0.0 <2.0.1
CVE IDs: CVE-2025-13984
Description: 
This module enables integration between Next.js and Drupal for headless CMS
functionality.

When installed, the module automatically enables cross-origin resource
sharing (CORS) with insecure default settings (Access-Control-Allow-Origin:
*), overriding any services.yml CORS configuration. This allows any origin to
make cross-origin requests to the site without administrator knowledge or
consent.

This vulnerability affects all installations as there are no configuration
options to disable this behavior.

Solution: 
There are two steps to resolve the issue: Install the latest version and
review your configuration,

  1) Update the module:
      * If you use the Next.js module for Drupal 10 or 11, upgrade to Next.js
        2.0.1 [3].
      * If you use the Next.js module for Drupal 9 (1.x branch), upgrade to
        Next.js 1.6.4 [4].

  2) After upgrading, review the CORS configuration in
     sites/default/services.yml. (See this module's CORS.md for details.).
     This is especially important if you previously relied on the automatic
     CORS configuration.
