📝 Summary: The GraphQL API's 'verifyAccountRecoveryPhoneNumber' mutation was found to be vulnerable to denial-of-service attacks through mutation aliasing. The vulnerability allowed multiple aliases of the same mutation to be included in a single request, causing the server to process each mutation sequentially and increasing the response time linearly. This resource exhaustion issue could potentially have led to service disruption for legitimate users.
