Affected scope and exposure questions

The current feed maps honojs/node-server (generic), @hono/node-server (npm), @hono/node-server (npm). Check affected ranges and fixed versions before updating.

Mapped affected packages and fixed versions
PackageAffected rangeFixed version

Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for honojs/node-server, @hono/node-server, @hono/node-server.
  2. 2Review the reported fix. Update honojs/node-server to 2.1.3; @hono/node-server to 2.1.3; @hono/node-server to 2.1.3 if you use the affected versions. Test the change in a non-production environment first.

Upstream source description

@hono/node-server allows running the Hono application on Node.js. 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.
