CVE-2026-47673
MediumSummary
Hono to framework aplikacji webowych wspierający dowolne środowisko JavaScript. W wersjach przed 4.12.21, middleware jwt i jwk nie weryfikowały, czy wartość nagłówka Authorization używa schematu Bearer, co pozwalało na autoryzację z użyciem poprawnego JWT pod innym identyfikatorem schematu.
Risk Assessment
Organizacje mogą być narażone na nieautoryzowany dostęp, ponieważ poprawne tokeny JWT mogą być akceptowane nawet przy użyciu nieprawidłowego schematu, co zagraża bezpieczeństwu aplikacji.
Recommendation
Zaleca się aktualizację do wersji 4.12.21 lub nowszej, aby zapewnić poprawną weryfikację nagłówka Authorization i zminimalizować ryzyko nieautoryzowanego dostępu.

Original NVD description (English source)
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.
