Overview

About vulnerability

Spring for GraphQL applications that have enabled the WebSocket transport are vulnerable to Cross-Site WebSocket Hijacking.

More precisely, an application is vulnerable when all the following are true:

  • the application has enabled the GraphQL WebSocket transport
  • the application relies on cookie-based session authentication
  • the application does not have custom Spring Security WebSocket-level Origin enforcement configured

When all the conditions above are met, an attacker can trick an authenticated user into visiting a malicious page, allowing the attacker to execute arbitrary GraphQL operations with the victim’s credentials.
