| Doc Text: |
A flaw was found in Hono, a web application framework. The `cx()` function within `hono/css` improperly handles class names during server-side rendering. This allows an attacker to inject untrusted values into a JSX class attribute, leading to the injection of arbitrary markup. This could result in Cross-Site Scripting (XSS) attacks, where malicious scripts can be executed in a user's browser.
