OSVDRUPAL-CONTRIB-2025-122 No score
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.
