Duplicate Advisory: hono/jsx renders plain strings unescaped in boundary components, leading to XSS
## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-hxh3-vqpv-xpqv. This link is maintained to preserve external references. ## Original Description hono before 4.13.7 fails to HTML-escape plain strings rendered by hono/jsx as a child or fallback of Suspense, as a string child of ErrorBoundary alongside an asynchronous sibling, as the single child of a Context.Provider, or as the root value passed to renderToString() or renderToReadableStream() from hono/jsx/dom/server. These paths stringify their input and treat the result as already-escaped markup, so an attacker who controls such a string during server-side rendering can inject arbitrary HTML and execute script under the application's origin.
