CVE-2025-30001

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.

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.

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.
