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...
