{"id":"CVE-2024-32652","aliases":["GHSA-hgxw-5xg3-69jx"],"url":"https://o3.security/vulnerability/CVE-2024-32652","summary":"@hono/node-server contains Denial of Service risk when receiving Host header that cannot be parsed","details":"### Impact\n\nThe application hangs when receiving a Host header with a value that `@hono/node-server` can't handle well. Invalid values are those that cannot be parsed by the `URL` as a hostname such as an empty string, slashes `/`, and other strings.\n\nFor example, if you have a simple application:\n\n```ts\nimport { serve } from '@hono/node-server'\nimport { Hono } from 'hono'\n\nconst app = new Hono()\n\napp.get('/', (c) => c.text('Hello'))\n\nserve(app)\n```\n\nSending a request with a Host header with an empty value to it:\n\n```\ncurl localhost:3000/ -H \"Host: \"\n```\n\nThe results:\n\n```\nnode:internal/url:775\n    this.#updateContext(bindingUrl.parse(input, base));\n                                   ^\n\nTypeError: Invalid URL\n    at new URL (node:internal/url:775:36)\n    at newRequest (/Users/yusuke/work/h/159/node_modules/@hono/node-server/dist/index.js:137:17)\n    at Server.<anonymous> (/Users/yusuke/work/h/159/node_modules/@hono/node-server/dist/index.js:399:17)\n    at Server.emit (node:events:514:28)\n    at Server.emit (node:domain:488:12)\n    at parserOnIncoming (node:_http_server:1143:12)\n    at HTTPParser.parserOnHeadersComplete (node:_http_common:119:17) {\n  code: 'ERR_INVALID_URL',\n  input: 'http:///'\n}\n```\n\n### Patches\n\nThe version `1.10.1` includes the fix for this issue. But, you should use `1.11.0`, which has other fixes related to this issue. https://github.com/honojs/node-server/issues/160 https://github.com/honojs/node-server/issues/161\n\n### Workarounds\n\nNothing. Upgrade your `@hono/node-server`.\n\n### References\n\nhttps://github.com/honojs/node-server/issues/159\n","published":"2024-04-19T18:29:42.857Z","modified":"2026-10-21T02:30:25.679873453Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":{"score":0.00882,"percentile":0.57219,"asOf":"2026-09-15"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"@hono/node-server","fixedVersion":"1.10.1"}],"fix":{"url":"https://github.com/honojs/node-server/commit/d847e60249fd8183ba0998bc379ba20505643204","label":"honojs/node-server@d847e60"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/32xxx/CVE-2024-32652.json"},{"type":"ADVISORY","url":"https://github.com/honojs/node-server/security/advisories/GHSA-hgxw-5xg3-69jx"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-32652"},{"type":"REPORT","url":"https://github.com/honojs/node-server/issues/159"},{"type":"FIX","url":"https://github.com/honojs/node-server/commit/d847e60249fd8183ba0998bc379ba20505643204"},{"type":"WEB","url":"https://github.com/honojs/node-server/issues/161"},{"type":"WEB","url":"https://github.com/honojs/node-server/commit/306d98f02a8671a0a1fb91ac8fe7e281690c05af"},{"type":"PACKAGE","url":"https://github.com/honojs/node-server"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-21T02:30:25.679873453Z"}}
