Overview

strawberry-graphql is an A library for creating GraphQL APIs

Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via the legacy graphql-ws protocol handler in strawberry/subscriptions/protocols/graphql_ws/handlers.py, where completed or failed subscription operations are not removed from the internal subscriptions and tasks bookkeeping dictionaries. Because these entries are never released, each completed operation continues to count against max_subscriptions_per_connection, and operation IDs cannot be reused. An attacker can exhaust the per-connection subscription slots by repeatedly opening and completing subscriptions, eventually preventing any new subscriptions from being established on that connection.
