CVE-2026-73474Network attack vectorHinoki check available

Server-side request forgery via insufficient input validation

Published Sep 2, 2026 · Updated Sep 2, 2026

Server-side request forgery in Drupal Entity Share Websub before 1.1.2 allows remote attackers to make server-side requests. Drupal states that certain inputs lack sufficient validation but does not identify the affected route, parameter, or request-building operation. The network path requires no authentication or user interaction, and successful requests can disclose data reachable from the Drupal server without altering it or interrupting service.
