Doc Text:
A flaw was found in Hono, a Web application framework. The hono/jsx component did not properly isolate context values per request during server-side rendering. This allowed data from a different in-flight request to be used after an asynchronous operation in a component. This could lead to information disclosure.

Description OSIDB Bzimport 2026-07-08 17:03:00 UTC
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.
