GraphQL Tools provides utilities for building, stitching, and mocking GraphQL schemas. Prior to version 1.1.36 of the GraphQL Tools legacy WebSocket executor package, buildWSLegacyExecutor in packages/executors/legacy-ws/src/index.ts retains request.extensions.connectionParams in the closure-scoped executorConnectionParams object after cleanupWebsocket closes a connection. When one executor is reused across different authorization contexts, a later request that omits a sensitive key can send an earlier caller's Authorization or tenant value in its connection_init payload, causing the downstream server to authenticate the later caller as the earlier user. Applications that create a new executor for every request are not affected. This issue is fixed in version 1.1.36 of the GraphQL Tools legacy WebSocket executor package.
