{"id":"CVE-2024-23340","aliases":["GHSA-rjq5-w47x-x359"],"url":"https://o3.security/vulnerability/CVE-2024-23340","summary":"@hono/node-server can't handle \"double dots\" in URL","details":"@hono/node-server is an adapter that allows users to run Hono applications on Node.js. Since v1.3.0, @hono/node-server has used its own Request object with `url` behavior that is unexpected. In the standard API, if the URL contains `..`, here called \"double dots\", the URL string returned by Request will be in the resolved path. However, the `url` in @hono/node-server's Request as does not resolve double dots, so `http://localhost/static/.. /foo.txt` is returned. This causes vulnerabilities when using `serveStatic`. Modern web browsers and a latest `curl` command resolve double dots on the client side, so this issue doesn't affect those using either of those tools. However, problems may occur if accessed by a client that does not resolve them. Version 1.4.1 includes the change to fix this issue. As a workaround, don't use `serveStatic`.\n\n","published":"2024-01-22T23:00:34.510Z","modified":"2026-07-15T01:49:12.135939861Z","cvss":{"score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":1,"affectedPackages":[{"ecosystem":"npm","name":"@hono/node-server","fixedVersion":"1.4.1"}],"fix":{"url":"https://github.com/honojs/node-server/commit/dd9b9a9b23e3896403c90a740e7f1f0892feb402","label":"honojs/node-server@dd9b9a9"},"references":[{"type":"WEB","url":"https://github.com/honojs/node-server/blob/8cea466fd05e6d2e99c28011fc0e2c2d3f3397c9/src/request.ts#L43-L45"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/23xxx/CVE-2024-23340.json"},{"type":"ADVISORY","url":"https://github.com/honojs/node-server/security/advisories/GHSA-rjq5-w47x-x359"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-23340"},{"type":"FIX","url":"https://github.com/honojs/node-server/commit/dd9b9a9b23e3896403c90a740e7f1f0892feb402"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:12.135939861Z"}}
