CVE-2025-53960

MediumCVSS 5.9/10Last modified Oct 7, 2026

Description

When issuing JSON Web Tokens (JWT), Apache StreamPark directly uses the user'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'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.
