Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Spring for GraphQL (spring-graphql) versions 2.0.0 through 2.0.3, 1.4.0 through 1.4.5, 1.3.0 through 1.3.8, and 1.0.0 through 1.0.6 are affected when the WebSocket transport is enabled. An attacker who tricks an authenticated user into visiting a malicious page can run arbitrary GraphQL operations with that user's credentials. Upgrade to spring-graphql 2.0.4 or 1.4.6, or the fixed release in your line.
