CVE-2026-89317
gose parsed the JWS crit header into JwsHeader.Crit and then never read it. RFC 7515 §4.1.11 requires a recipient to reject a JWS whose listed critical extension parameters it does not understand. gose implements no header extensions, so every token carrying a non-empty crit should have been...
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
"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-2026-89317
The gose library is vulnerable because JwtVerifierImpl.Verify fails to enforce the JWS crit header as required by RFC 7515 §4.1.11 . While the library correctly parses the crit header into JwsHeader.Crit, it fails to act on it. Since gose does not implement header extensions, any token containing...

Eclipse KeyPont - GOSE input validation error vulnerability
Eclipse KeyPont – Versions 0.7.3 through 0.13.0-rc1 and versions prior to 1.0.0-rc4 of GOSE contain a security vulnerability. This vulnerability arises because the JWS Crit header is parsed but not read, resulting in tokens containing unsupported critical extension parameters being accepted inste...
