Vulnerability Title
Hono: Unvalidated JSX Tag Names in hono/jsx May Allow HTML Injection
Source: NVD (National Vulnerability Database)
Vulnerability Description
Hono is a Web application framework that provides support for any JavaScript runtime. Prior to 4.12.16, Improper handling of JSX element tag names in hono/jsx allowed unvalidated tag names to be directly inserted into the generated HTML output. When untrusted input is used as a tag name via the programmatic jsx() or createElement() APIs during server-side rendering, specially crafted values may break out of the intended element context and inject unintended HTML. This vulnerability is fixed in 4.12.16.
