CVE-2026-116585 Go JOSE: Panic during CBC-HMAC processing

Go JOSE provides an implementation of the Javascript Object Signing and Encryption set of standards in Go, including support for JSON Web Encryption JWE, JSON Web Signature JWS, and JSON Web Token JWT standards. Prior to 4.1.5, decrypting untrusted JWE ciphertext with A128CBC-HS256, A192CBC-HS384...

CVE-2026-116585

The Go JOSE library (prior to version 4.1.5 ) is vulnerable to a denial of service due to a panic during CBC-HMAC processing. When decrypting untrusted JWE ciphertext using the A128CBC-HS256 , A192CBC-HS384 , or A256CBC-HS512 content-encryption algorithms, the system may pass an empty ciphertext ...

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...

CVE-2026-89320

The gose library is vulnerable because the HmacShaCryptor.Hash function fails to hash its input, consistently returning HMAC_K("") (the MAC of an empty message). This flaw causes all AES-CBC-HMAC JWE tokens produced or verified by the library to carry an authentication tag that is constant for a ...

CVE-2026-89320 HmacShaCryptor.Hash never hashes its input — returns constant HMAC_K("") for all inputs, voiding CBC-HMAC JWE integrity

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...
