CVE-2026-22818

CVE-2026-22818 concerns Hono’s JWK/JWKS JWT verification middleware. Prior to 4.11.4, if a JWK did not explicitly specify an algorithm, the middleware could derive the signature verification algorithm from the untrusted JWT header’s alg value, enabling algorithm confusion and potentially forged t...

CVE-2026-22818 JWT algorithm confusion in Hono JWK Auth Middleware when JWK lacks "alg" (untrusted header.alg fallback)

Hono is a Web application framework that provides support for any JavaScript runtime. Prior to 4.11.4, there is a flaw in Hono’s JWK/JWKS JWT verification middleware allowed the algorithm specified in the JWT header to influence signature verification when the selected JWK did not explicitly defi...
