The record
Hono is a Web application framework that provides support for any JavaScript runtime. Prior to version 4.11.7, a Cross-Site Scripting (XSS) vulnerability exists in the `ErrorBoundary` component of the hono/jsx library. Under certain usage patterns, untrusted user-controlled strings may be rendered as raw HTML, allowing arbitrary script execution in the victim's browser. Version 4.11.7 patches the issue.
