Hono is a web framework written in TypeScript. Prior to version 3.11.7, clients may override named path parameter values from previous requests if the application is using TrieRouter. So, there is a risk that a privileged user may use unintended parameters when deleting REST API resources. TrieRouter is used either explicitly or when the application matches a pattern that is not supported by the default RegExpRouter. Version 3.11.7 includes the change to fix this issue. As a workaround, avoid using TrieRouter directly.

Affected: npm: hono

### Impact

The clients may override named path parameter values from previous requests if the application is using TrieRouter. So, there is a risk that a privileged user may use unintended parameters when deleting REST API resources.

TrieRouter is used either explicitly or when the application matches a pattern that is not supported by the default RegExpRouter.

The code to reproduce it. The server side application:

```ts import { Hono } from 'hono' import { TrieRouter } from 'hono/router/trie-router'

const wait = async (ms: number) => { return new Promise((resolve) => { setTimeout(resolve, ms) }) }

const app = new Hono({ router: new TrieRouter() })

app.use('*', async (c, next) => { await wait(Math.random() * 200) return next() })

app.get('/modules/:id/versions/:version', async (c) => { const id = c.req.param('id') const version = c.req.param('version')

console.log('path', c.req.path) console.log('version', version)

return c.json({ id, version, }) })

export default app ```

The client code which makes requests to the server application:

```ts const examples = [ 'http://localhost:8787/modules/first/versions/first', 'http://localhost:8787/modules/second/versions/second', 'http://localhost:8787/modules/third/versions/third', ]

const test = () => { for (const example of examples) { fetch(example) .then((response) => response.json()) .then((data) => { const splitted = example.split('/') const expe…
