CyberRota Analysis

AI-Generated

The Hono web application framework for JavaScript runtimes is vulnerable due to improper isolation of context values during server-side rendering, potentially allowing data from one request to leak into another. This could lead to unauthorized access to sensitive information across different user sessions. Developers and organizations using Hono versions 4.11.8 through 4.12.26 should prioritize upgrading to version 4.12.27 to mitigate this risk.

Original NVD Description

Hono is a Web application framework that provides support for any JavaScript runtime. From 4.11.8 before 4.12.27, hono/jsx did not isolate context values per request during server-side rendering, allowing createContext, useContext, jsxRenderer, or useRequestContext data from a different in-flight request to be used after an await in an async component. This issue is fixed in version 4.12.27.
