For any input it returned `HMAC_K(&#34;&#34;)` — the MAC of the empty message under the key. Every AES-CBC-HMAC JWE produced or verified by gose therefore carried an authentication tag that is constant per key and independent of the message, removing ciphertext integrity entirely.</p> <p><strong>Affected:</strong> Eclipse Foundation Eclipse KeyPont - GOSE</p> <p>`HmacShaCryptor.Hash` never hashed its input.
