Kerentanan Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') pada hono. Skor CVSS 3.1 6.1 (Medium) menurut github.com.

Deskripsi (NVD)

Hono is a Web application framework that provides support for any JavaScript runtime. From 4.0.0 before 4.12.27, cx() in hono/css composes class names from plain strings but marks the result as already escaped without HTML-escaping the input, allowing untrusted className values used in a JSX class attribute during server-side rendering to break out of the attribute and inject arbitrary markup. This issue is fixed in version 4.12.27.
