Original NVD Description

inversoft prime-jwt version prior to commit abb0d479389a2509f939452a6767dc424bb5e6ba contains a CWE-20 vulnerability in JWTDecoder.decode that can result in an incorrect signature validation of a JWT token. This attack can be exploitable when an attacker crafts a JWT token with a valid header using 'none' as algorithm and a body to requests it be validated. This vulnerability was fixed after commit abb0d479389a2509f939452a6767dc424bb5e6ba.
