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."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"honojs","product":"node-server","versions":[{"version":"> = 1.19.10, < 2.1.3","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","baseScore":5.3,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"NONE","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":1.4}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Primary","description":[{"lang":"en","value":"CWE-174"}]}],"references":[{"url":"https://github.com/honojs/node-server/commit/982179278529d5673812116b042829f27794966f","source":"security-advisories@github.com"},{"url":"https://github.com/honojs/node-server/releases/tag/v2.1.3","source":"security-advisories@github.com"},{"url":"https://github.com/honojs/node-server/security/advisories/GHSA-rmxm-3fg6-px4f","source":"security-advisories@github.com"}]}
