Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
juniper_hyper versions before 0.10.1 read the entire body of a POST request into memory in the graphql() and graphql_sync() functions, with no size limit. An unauthenticated client can send a very large body and exhaust the server's memory. Upgrade to juniper_hyper 0.10.1, which reads at most 2 MiB by default and returns 413 Payload Too Large for larger bodies; the limit can be changed per request with a BodyLimit in the request extensions.
