Low risk16th percentile - higher than 16% of all known CVEs
Summary
Apache StreamPark directly uses the user's password as the HMAC signing key (e.g., with the HS256 algorithm) when issuing JWT tokens. An attacker can exploit this to perform offline brute-force attacks on the user's password using a captured JWT, or to forge identity tokens if the password is known, leading to complete account takeover.
Risk Assessment
An attacker can take over a user account, potentially leading to unauthorized access to data and functions. The risk affects Apache StreamPark installations from version 2.0.0 before 2.1.7.
Recommendation
Update Apache StreamPark to version 2.1.7 or later, which fixes this vulnerability.
Other vulnerabilities in Apache StreamPark
See all- CVE-2025-54947Critical
In Apache StreamPark versions 2.0.0 through 2.1.7, a security vulnerability involving a hard-coded encryption key exists. The system uses a fixed, immutable key for encryption instead of dynamically generating or securely configuring the key. Attackers may obtain this key through reverse engineering or code analysis, potentially decrypting sensitive data or forging encrypted information, leading to information disclosure or unauthorized system access.
- CVE-2025-54981High
Weak Encryption Algorithm in Apache StreamPark: the use of an AES cipher in ECB mode and a weak random number generator for encrypting sensitive data, including JWT tokens, may have risked exposing sensitive authentication data. This affects versions from 2.0.0 before 2.1.7. Users are recommended to upgrade to version 2.1.7.
Original NVD description (English source)
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.
