CVE-2026-29087: @hono/node-server has authorization bypass for protected static paths via encoded slashes in Serve Static Middleware

When using @hono/node-server’s static file serving together with route-based middleware protections (e.g. protecting /admin/*), inconsistent URL decoding can allow protected static resources to be accessed without authorization.

In particular, paths containing encoded slashes (%2F) may be evaluated differently by routing/middleware matching versus static file path resolution, enabling a bypass where middleware does not run but the static file is still served.
