{"id":"CVE-2026-44456","aliases":["GHSA-9vqf-7f2p-gf9v"],"url":"https://o3.security/vulnerability/CVE-2026-44456","summary":"Hono: bodyLimit() can be bypassed for chunked / unknown-length requests","details":"Hono is a Web application framework that provides support for any JavaScript runtime. Prior to 4.12.16, bodyLimit() does not reliably enforce maxSize for requests without a usable Content-Length (e.g. Transfer-Encoding: chunked). Oversized requests can reach handlers and return 200 instead of 413. This vulnerability is fixed in 4.12.16.","published":"2026-05-13T14:58:08.451Z","modified":"2026-08-07T11:31:21.177379399Z","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"hono","fixedVersion":"4.12.16"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44456.json"},{"type":"ADVISORY","url":"https://github.com/honojs/hono/security/advisories/GHSA-9vqf-7f2p-gf9v"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44456"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:31:21.177379399Z"}}
