From 4.12.4 until 4.13.11, serveStatic can interpret a malformed percent-encoded path differently from upstream routing middleware and bypass protection for a static prefix. The root cause is serveStatic decodes a routed request path a second time before filesystem lookup. The attack mechanism is malformed percent encoding survives the first routing interpretation and becomes a protected path only during the later static-file decode. The affected component is serveStatic. The trigger conditions are an application protects a static prefix with upstream middleware and serveStatic receives an attacker-controlled malformed percent-encoded path. The impact is unauthorized disclosure of a static file that upstream middleware was intended to protect. The issue does not permit traversal outside the configured static root. This issue is fixed in version 4.13.11.","state":0,"publishedAt":"2026-10-19T18:17:00.407+00:00","modifiedAt":"2026-10-20T17:17:29.443+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3,"severity":"MEDIUM"}],"references":["https://github.com/honojs/hono/commit/8b05c774ef1555c70f5ba5e2991b7e77cc3635cc","https://github.com/honojs/hono/security/advisories/GHSA-5r4p-p66f-jhc7"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-111757","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-174"],"productCriteria":[],"sourceDates":{"published":"2026-10-19T18:17:00.407","lastModified":"2026-10-20T17:17:29.443"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
