Severity
CWE	CWE-327: Use of a Broken or Risky Cryptographic Algorithm
OWASP	A03:2017 - Sensitive Data Exposure
Confidence Level	Low
Impact Level	Medium
Likelihood Level	Low

Description

The code is creating JWT tokens with the 'none' algorithm, which means the tokens are not cryptographically signed. This allows anyone to forge or modify tokens without detection, making authentication insecure.

Impact

If exploited, attackers can generate or alter JWT tokens to impersonate users or escalate privileges, bypassing authentication. This can lead to unauthorized access to sensitive data or critical actions in your application.
