CVE-2025-54947 — In Apache StreamPark versions 2.0.0 through 2.1.7, a security vulnerability involving a hard-coded encryption key exists

Critical CVSS 9.8

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.

Authentication bypass and missing authentication

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map every affected endpoint and protocol path, including alternate ports, legacy routes, recovery flows, service accounts, and machine-to-machine access.
  • Confirm which deployments enable the affected authentication mode and whether the interface is reachable from untrusted networks.
  • Review session, token, credential, and proxy trust configuration without attempting account takeover.

Remediate safely

  • Apply the supported fix and centralize fail-closed authentication before protected request handling.
  • Remove default or embedded credentials, rotate affected secrets and sessions, and bind authentication decisions to the intended audience and channel.
  • Add negative tests for alternate routes, malformed or absent credentials, recovery flows, and proxy-derived identity.
