v4.6.5

Security fix for CSRF Protection Middleware

This release includes a security fix for CSRF Protection Middleware. If you are using CSRF Protection Middleware, please upgrade this hono package immediately.

Before this release, a request without a Content-Type header can bypass the protection. This fix does not allow it. See: GHSA-2234-fmw7-43wr

v4.6.0

Hono v4.6.0 is now available!

One of the highlights of this release is the Context Storage Middleware. Let's introduce it.

Context Storage Middleware

Many users may have been waiting for this feature. The Context Storage Middleware uses AsyncLocalStorage to allow handling of the current Context object even outside of handlers.

For example, let’s define a Hono app with a variable message: string.

type Env = {
  Variables: {
    message: string
  }
}

const app = new Hono<Env>()

To enable Context Storage Middleware, register contextStorage() as middleware at the top and set the message value.

import { contextStorage } from 'hono/context-storage'

//...

app.use(contextStorage())

app.use(async (c, next) => {
  c.set('message', 'Hello!')
  await next()
})

getContext() returns the current Context object, allowing you to get the value of the message variable outside the handler.

import { getContext } from 'hono/context-storage'

app.get('/', (c) => {
  return c.text(getMessage())
})

// Access the variable outside the handler.
const getMessage = () => {
  return getContext<Env>().var.message
}

In the case of Cloudflare Workers, you can also access the Bindings outside the handler by using this middleware.

type Env = {
  Bindings: {
    KV: KVNamespace
  }
}

const app = new Hono<Env>()

app.use(contextStorage())

const setKV = (value: string) => {
  return getContext<Env>().env.KV.put('key', value)
}

Thanks @marceloverdijk !

v4.5.8

Security Fix for CSRF Protection Middleware

Before this release, in versions 4.5.7 and below, the CSRF Protection Middleware did not treat requests including Content-Types with uppercase letters (e.g., Application/x-www-form-urlencoded) as potential attacks, allowing them to pass.

This could cause unexpected behavior, leading to a vulnerability. If you are using the CSRF Protection Middleware, please upgrade to version 4.5.8 or higher immediately.
