The functions had no limit on the size of the body. A client could thus send a large body and exhaust the memory of the server. The request needs no authentication.\n\n`juniper_hyper` 0.10.1 reads at most 2 MiB of a request body by default. The functions respond with `413 Payload Too Large` to larger bodies. A `juniper_hyper::BodyLimit` in the extensions of a request changes the limit for the request.","affected":[{"package":{"name":"juniper_hyper","ecosystem":"crates.io","purl":"pkg:cargo/juniper_hyper"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0.0.0-0"},{"fixed":"0.10.1"}]}],"ecosystem_specific":{"affected_functions":null,"affects":{"arch":[],"functions":[],"os":[]}},"database_specific":{"categories":["denial-of-service"],"cvss":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","informational":null,"source":"https://github.com/rustsec/advisory-db/blob/osv/crates/RUSTSEC-2026-0415.json"}}],"references":[{"type":"PACKAGE","url":"https://crates.io/crates/juniper_hyper"},{"type":"ADVISORY","url":"https://rustsec.org/advisories/RUSTSEC-2026-0415.html"},{"type":"WEB","url":"https://github.com/graphql-rust/juniper/pull/1405"}],"database_specific":{"license":"CC0-1.0"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
