Overview
Affected versions of this package are vulnerable to Authentication Bypass by Spoofing due to a flaw in the JWT authentication mechanism. An attacker can bypass the issue ("iss") check and gain unauthorized access by using a forged token. If two servers use the same pair of keys, the attacker can use the token from the first server to deceive the second server, and cause the privilege escape.
