Apache StreamPark Vulnerability Let Attackers Access Sensitive Data

A critical security vulnerability has been discovered in Apache StreamPark that could allow attackers to decrypt sensitive information and gain unauthorized system access.

The vulnerability stems from the use of a hard-coded encryption key in the application, which enables threat actors to bypass security controls via reverse engineering or code analysis.

The vulnerability, tracked as CVE-2025-54947, affects Apache StreamPark versions 2.0.0 through 2.1.7.

The flaw arises because the system relies on a fixed, immutable key for encryption operations rather than implementing dynamic key generation or secure configuration practices.

Field	Details
CVE Identifier	CVE-2025-54947
Vulnerability Type	Hard-coded Encryption Key
Affected Versions	Apache StreamPark 2.0.0 – 2.1.7
Vulnerability Impact	Information Disclosure, Unauthorized Access

This design weakness creates a significant exposure window for organizations using affected versions.

Apache StreamPark Vulnerability

Threat actors exploiting this vulnerability could decrypt sensitive data stored within StreamPark installations or forge encrypted information to execute unauthorized operations.

The impact extends beyond simple data exposure, as attackers could leverage the compromised encryption to manipulate system behavior or escalate privileges within the infrastructure.

Apache StreamPark, a unified stream-processing platform that simplifies big data streaming, is widely deployed in enterprise environments for real-time data processing.

Organizations relying on this platform for critical data operations face increased risk until they apply the required security patches.

The Apache StreamPark development team has released version 2.1.7, which resolves the hard-coded key vulnerability.

Security experts and system administrators are strongly advised to upgrade affected installations to version 2.1.7 immediately to eliminate the security risk.

Organizations should also conduct a security audit of their StreamPark deployments to identify if sensitive data has been accessed through this vulnerability.

Additionally, reviewing encryption key management practices across the infrastructure is recommended to prevent similar vulnerabilities from emerging.
