{"id":"CVE-2026-118663","published":"2026-10-28T21:16:56.543","lastModified":"2026-10-28T21:16:56.543","description":"@hono/node-server allows running the Hono application on Node.js. From 1.19.10 until 2.1.3, serveStatic decodes a request path a second time after Hono has already decoded it for routing, so a malformed percent-encoded sequence can make route middleware evaluate an encoded path while static file resolution uses a different directory. An unauthenticated attacker can bypass middleware mounted on a protected static prefix and read a file inside the configured static root, although the flaw does not permit traversal outside that root. This issue is fixed in version 2.1.3.","cvssScore":5.3,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","cwes":["CWE-174"],"vendors":[],"products":[],"references":[{"url":"https://github.com/honojs/node-server/commit/982179278529d5673812116b042829f27794966f","tags":[]},{"url":"https://github.com/honojs/node-server/releases/tag/v2.1.3","tags":[]},{"url":"https://github.com/honojs/node-server/security/advisories/GHSA-rmxm-3fg6-px4f","tags":[]}],"exploitRefs":[{"url":"https://github.com/honojs/node-server/commit/982179278529d5673812116b042829f27794966f","tags":[]},{"url":"https://github.com/honojs/node-server/releases/tag/v2.1.3","tags":[]},{"url":"https://github.com/honojs/node-server/security/advisories/GHSA-rmxm-3fg6-px4f","tags":[]}],"hasPoc":true,"ai":null}
