Overview
Affected versions of this package are vulnerable to Uncontrolled Recursion via 'jose_jwk:shared_secret/2' (exposed in Elixir as JOSE.JWK.shared_secret/2) derives an ECDH shared secret from two JWKs. When provided with two JWKs of differing key types (such as EC and RSA), its fallback clause repeatedly re-invokes itself with the unchanged inputs, triggering an infinite tail-recursive loop that never terminates or crashes. An unauthenticated attacker supplying a mismatched public key can trap an Erlang scheduler at 100% CPU usage, rapidly exhausting all available schedulers and causing a denial of service.
