4.11.4

Security

Fixed a JWT algorithm confusion issue in the JWT and JWK/JWKS middleware.

Both middlewares now require an explicit algorithm configuration to prevent the verification algorithm from being influenced by untrusted JWT header values.

If you are using the JWT or JWK/JWKS middleware, please update to the latest version as soon as possible.

JWT middleware

import { jwt } from 'hono/jwt'

app.use(
  '/auth/*',
  jwt({
    secret: 'it-is-very-secret',
    alg: 'HS256', // required
  })
)

JWK/JWKS middleware

import { jwk } from 'hono/jwk'

app.use(
  '/auth/*',
  jwk({
    jwks_uri: 'https://example.com/.well-known/jwks.json',
    alg: ['RS256'], // required (asymmetric algorithms only)
  })
)
