CVE-2026-89320

HmacShaCryptor.Hash never hashed its input. For any input it returned HMACK"" — 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...

cjose: OpenIDC/cjose uses all-zero Content Encryption Key for AES-CBC-HMAC JWE encryption

A flaw was found in cjose. When encrypting a JSON Web Encryption JWE object using AES-CBC-HMAC algorithms, the library initializes the encryption key with all-zero bytes instead of generating a secure random key. As a result, an attacker who intercepts the encrypted message can decrypt sensitive...
