CVE-2026-47673

Hono is a Web application framework that provides support for any JavaScript runtime. Prior to 4.12.21, the jwt and jwk middlewares do not verify that the Authorization header value uses theBearer scheme. Any two-part header value — regardless of the scheme name in the first position — proceeds to JWT verification. A request presenting a valid JWT under a non-Bearer scheme identifier (such as Basic or Token) is authenticated identically to a correctly formed Bearer request. This vulnerability is fixed in 4.12.21.

Summary		(es) Hono es un framework de aplicación web que proporciona soporte para cualquier entorno de ejecución de JavaScript. Antes de 4.12.21, los middlewares jwt y jwk no verifican que el valor del encabezado de autorización utilice el esquema Bearer. Cualquier valor de encabezado de dos partes - independientemente del nombre del esquema en la primera posición - procede a la verificación JWT. Una solicitud que presenta un JWT válido bajo un identificador de esquema que no sea Bearer (como Basic o Token) se autentica de forma idéntica a una solicitud Bearer correctamente formada. Esta vulnerabilidad se corrige en 4.12.21.
