Description

In Apache StreamPark versions 2.0.0 through 2.1.7, a security vulnerability involving a hard-coded encryption key exists. This vulnerability occurs because 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. 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.

Affected products

• Apache Software Foundation Apache StreamPark: from 2.0.0 before 2.1.7 — fixed in 2.1.7

How to fix

Upgrade to a fixed version: Apache Software Foundation Apache StreamPark 2.1.7. Check the vendor advisory for mitigations.
