CVE-2026-1180

A flaw was identified in Keycloak’s OpenID Connect Dynamic Client Registration feature when clients authenticate using privatekeyjwt. The issue allows a client to specify an arbitrary jwksuri, which Keycloak then retrieves without validating the destination. This enables attackers to coerce the...

CVE-2026-22818

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...

Hono JWK Auth Middleware has JWT algorithm confusion when JWK lacks "alg" (untrusted header.alg fallback)

Summary 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 define an algorithm. This could enable JWT algorithm confusion and, in certain configurations, allow forged...

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...

Improper Encoding or Escaping of Output

Overview get-jwks is a Fetch utils for JWKS keys Affected versions of this package are vulnerable to Improper Encoding or Escaping of Output via the JWKS cache process. An attacker can bypass issuer validation by poisoning the cache with keys from an unexpected issuer and subsequently leveraging...

get-jwks: poisoned JWKS cache allows post-fetch issuer validation bypass

Summary A vulnerability in get-jwks can lead to cache poisoning in the JWKS key-fetching mechanism. Details When the iss issuer claim is validated only after keys are retrieved from the cache, it is possible for cached keys from an unexpected issuer to be reused, resulting in a bypass of issuer...
