Go to dashboardLoadPublicKey resolves an EC key's curve with an unchecked type assertion, so a JWK with kty EC and a non-EC alg value makes the parser panic. An attacker who can supply such a key crashes the process that parses it, a denial of service.

LoadPublicKey resolved an EC key's curve with an unchecked type assertion, algToOptsMap[alg].(*ECDSAOptions). A JWK declaring "kty":"EC" together with a non-EC "alg" — which RFC 7517 §4.4 permits — reaches that assertion and panics.
