CVE-2025-13984Network attack vectorHinoki check available

Access bypass via forced wildcard CORS

Published Jan 28, 2026 · Updated Jan 28, 2026

Permissive CORS in Drupal Next.js before 1.6.4 and 2.0.0 allows remote attackers to issue requests from any web origin. The module automatically sets Access-Control-Allow-Origin to a wildcard and overrides the site's services.yml CORS configuration without an opt-out. Every affected installation exposes the behavior; exploitation requires a user browser to load attacker-controlled web content, enabling cross-origin access to Drupal responses.
