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":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3,"severity":null}],"references":["https://github.com/honojs/hono/security/advisories/GHSA-5r4p-p66f-jhc7","https://github.com/honojs/hono/commit/8b05c774ef1555c70f5ba5e2991b7e77cc3635cc"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-104537","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Oct 19, 2026, 5:31:20 PM","dateUpdated":"Oct 20, 2026, 4:10:30 PM"},"relatedAdvisories":[{"id":"RHSA-2026:85295","title":"Red Hat Security Advisory: Red Hat Hardened Images RPMs bug fix and enhancement update","vulnerabilityIds":["CVE-2026-92539","CVE-2026-93294","CVE-2026-111757"]},{"id":"RHSA-2026:85544","title":"Red Hat Security Advisory: Red Hat Hardened Images RPMs bug fix and enhancement update","vulnerabilityIds":["CVE-2026-15577","CVE-2026-33374","CVE-2026-92539","CVE-2026-93294","CVE-2026-95502","CVE-2026-111757"]}],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
