  "title": "Prototype pollution via graphql-yoga dependency in @denext/graphql",
  "summary": "@denext/graphql versions before 0.7.0 may resolve graphql-yoga with a vulnerable @graphql-tools/utils dependency. An attacker may be able to alter JavaScript object prototypes through affected GraphQL result-merging behavior when the application uses the relevant merge paths. Exposure requires the lockfile to retain graphql-yoga 5.24.3 or earlier.",
  "mitigation": "Upgrade @denext/graphql to version 0.7.0. Also update the lockfile so graphql-yoga resolves to 5.24.4 or later; pinning graphql-yoga to 5.24.6 or later reduces exposure.",
