  "title": "Unbounded parser recursion in webonyx graphql-php",
  "summary": "webonyx graphql-php versions before 15.32.3 can consume the PHP call stack while parsing excessively nested GraphQL input. A remote attacker able to submit requests to a GraphQL endpoint can terminate affected worker or long-running PHP processes; validation and complexity limits do not prevent this condition.",
  "mitigation": "Upgrade graphql-php to version 15.32.3 or later. Until the upgrade is complete, restrict untrusted access to GraphQL endpoints and enforce request-size or nesting controls at an upstream gateway where possible.",
