Severity
CWE	CWE-345: Insufficient Verification of Data Authenticity
OWASP	A08:2021 - Software and Data Integrity Failures
Confidence Level	Medium
Impact Level	Low
Likelihood Level	Low

Description#

The code is decoding JWT tokens using ParseUnverified, which extracts token data without verifying its signature. This means anyone can tamper with the token contents and the code will still trust them as valid.

Impact#

If exploited, attackers could forge or modify JWT tokens to gain unauthorized access, escalate privileges, or manipulate user data. This undermines authentication and authorization, leading to serious security breaches such as account takeover or data exposure.
