  "summary": "graphql-core versions before 3.2.12 and 3.3.0rc1 can fail to account for comments when enforcing the parser's token limit.

  "mitigation": "Upgrade graphql-core to 3.2.12 or 3.3.0rc1. Until upgrading, enforce a size limit on the decompressed request body before it reaches the GraphQL parser.",
