CVE-2025-30001 is a security vulnerability identified in Apache StreamPark, an open-source real-time data streaming and processing platform maintained by the Apache Software Foundation. The vulnerability is classified under CWE-279, which pertains to incorrect execution-assigned permissions. This means that during the execution of certain processes or commands within StreamPark versions 2.1.4 up to but not including 2.1.6, permissions are assigned improperly, potentially granting users or processes higher privileges than intended. Such misconfigurations can lead to unauthorized access or privilege escalation, allowing attackers to execute actions beyond their authorized scope. Although no public exploits have been reported, the flaw poses a significant risk because it undermines the security model of the application. The issue was reserved in March 2025 and published in October 2025, with the Apache Software Foundation releasing version 2.1.6 to remediate the problem. The vulnerability does not require user interaction, and exploitation could be possible by an attacker with some level of access to the system, making it a critical concern for environments relying on StreamPark for data streaming and processing.

For European organizations, the impact of CVE-2025-30001 can be substantial, especially for those leveraging Apache StreamPark in critical data processing pipelines, financial services, telecommunications, and industrial control systems. Unauthorized permission assignments can lead to privilege escalation, allowing attackers to manipulate data streams, disrupt service availability, or exfiltrate sensitive information. This could compromise data integrity and confidentiality, potentially leading to regulatory non-compliance under GDPR and other data protection laws. The disruption of real-time data processing could also affect operational continuity and decision-making processes. Given the increasing reliance on streaming platforms for real-time analytics and automation, the vulnerability could have cascading effects on business operations and critical infrastructure within Europe.

Organizations should immediately upgrade Apache StreamPark to version 2.1.6 or later, where this vulnerability has been fixed. Beyond upgrading, it is crucial to audit and enforce strict permission and role-based access controls within StreamPark deployments to ensure the principle of least privilege is maintained. Regularly review execution policies and monitor logs for unusual permission changes or unauthorized actions. Implement network segmentation to limit access to StreamPark management interfaces and data streams. Employ application-layer firewalls and intrusion detection systems tailored to streaming data environments to detect anomalous behavior. Additionally, integrate vulnerability management processes to track and apply security patches promptly. Conduct security training for administrators on secure configuration and permission management specific to Apache StreamPark.
