Description

When issuing JSON Web Tokens (JWT), Apache StreamPark directly uses the user&#39;s password as the HMAC signing key (e.g., with the HS256 algorithm). An attacker can exploit this vulnerability to perform offline brute-force attacks on the user&#39;s password using a captured JWT, or to arbitrarily forge identity tokens for the user if the password is already known, ultimately leading to complete account takeover. This issue affects Apache StreamPark: from 2.0.0 before 2.1.7. Users are recommended to upgrade to version 2.1.7, which fixes the issue.
