Overview
org.springframework.graphql:spring-graphql is a GraphQL Support for Spring Applications
Affected versions of this package are vulnerable to Origin Validation Error via insufficient Origin validation for WebSocket connections. An attacker can perform Cross-Site WebSocket Hijacking (CSWSH) by inducing an authenticated user to visit a malicious website that establishes a WebSocket connection to the vulnerable application. If cookie-based session authentication is used and WebSocket Origin checks are not enforced, the attacker can execute arbitrary GraphQL operations using the victim's authenticated session.
Note: This is only exploitable if the application has enabled the GraphQL WebSocket transport, relies on cookie-based session authentication, and does not implement custom Spring Security WebSocket Origin enforcement.
