CVE-2026-109955 [MEDIUM] – Hono from 4.12.4 before 4.13.11 contains a middleware bypass vulnerability in serveStatic

Hono from 4.12.4 before 4.13.11 contains a middleware bypass vulnerability in serveStatic that allows unauthenticated attackers to skip prefix middleware by exploiting double path decoding. Attackers can send malformed percent-encoded paths that the router matches in encoded form, reaching static files without authentication checks running.
