Description: vlife through 2.0.1 contains an authentication bypass vulnerability that allows unauthenticated attackers to forge JWTs using the hardcoded HS256 signing key in TokenUtil. Attackers can sign a token with superUser=true and arbitrary groupIds claims to gain super administrator access to any URL on vlife instances.
