Prior to version 0.4.2, `conduit-hyper` did not check any limit on a request's length before calling [`hyper::body::to_bytes`](https://docs.rs/hyper/latest/hyper/body/fn.to_bytes.html). An attacker could send a malicious request with an abnormally large `Content-Length`, which could lead to a panic if memory allocation failed for that request. In version 0.4.2, `conduit-hyper` sets an internal limit of 128 MiB per request, otherwise returning status 400 (\"Bad Request\"). This crate is part of the implementation of Rust's [crates.io](https://crates.io/), but that service is not affected due to its existing cloud infrastructure, which already drops such malicious requests. Even with the new limit in place, `conduit-hyper` is not recommended for production use, nor to directly serve the public Internet.","state":0,"publishedAt":"2022-10-31T19:15:10.593+00:00","modifiedAt":"2026-06-17T04:58:05.317+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"},{"system":"CVSS 3.1 · nvd@nist.gov · Primary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"}],"references":["https://github.com/conduit-rust/conduit-hyper/security/advisories/GHSA-9398-5ghf-7pr6"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2022-39294","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Modified","weaknesses":["CWE-400","CWE-1284"],"productCriteria":["cpe:2.3:a:conduit-hyper_project:conduit-hyper:*:*:*:*:*:rust:*:*","cpe:2.3:a:conduit-hyper_project:conduit-hyper:0.2.0:-:*:*:*:rust:*:*","cpe:2.3:a:conduit-hyper_project:conduit-hyper:0.2.0:alpha3:*:*:*:rust:*:*","cpe:2.3:a:conduit-hyper_project:conduit-hyper:0.2.0:alpha4:*:*:*:rust:*:*"],"sourceDates":{"published":"2022-10-31T19:15:10.593","lastModified":"2026-06-17T04:58:05.317"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
