Overview
Affected versions of this package are vulnerable to Insufficient Verification of Data Authenticity due to the lack of validation for the nonce parameter in the authentication process. An attacker can gain unauthorized access by replaying a previously obtained valid ID token, allowing authentication as another user within the token's validity period. This is only exploitable if an attacker is able to intercept or obtain a valid ID token for a target user.
