A high-severity vulnerability has been identified in Apache StreamPark, which could allow an attacker to execute code with higher privileges than intended. Successful exploitation could lead to unauthorized access to sensitive data, modification of system files, or complete compromise of the affected server. Organizations using the affected software are at significant risk of data breaches and service disruption.

This vulnerability, classified as Incorrect Execution-Assigned Permissions, exists within the job submission and execution component of Apache StreamPark. An authenticated attacker can submit a specially crafted data processing job that, due to improper permission handling, is executed with the elevated privileges of the StreamPark service account instead of the user's restricted permissions. This allows the attacker's code to break out of its intended operational sandbox and interact directly with the underlying operating system of the server hosting StreamPark.

This vulnerability is rated as high severity with a CVSS score of 7.3. Exploitation could have a severe impact on business operations, leading to unauthorized access, modification, or exfiltration of sensitive data being processed by StreamPark. An attacker could leverage this flaw to execute arbitrary commands on the server, potentially leading to a full system compromise, lateral movement within the network, service disruption, and significant reputational damage from a resulting data breach.

Immediate Action: Apply the security updates released by Apache to all affected StreamPark instances immediately, prioritizing internet-facing or critical systems. After patching, review system and application logs for any signs of compromise that may have occurred prior to the update.

Proactive Monitoring: Security teams should monitor for anomalous activity on StreamPark servers, including unexpected processes being spawned by the StreamPark service user, unusual network connections originating from the server, and attempts to access or modify files outside of the application's standard directories. Review StreamPark application logs for unusually structured or suspicious job submissions.

Compensating Controls: If immediate patching is not feasible, organizations should implement the following controls:

• Restrict network access to the StreamPark management interface to only trusted administrative hosts.
• Enforce the principle of least privilege by ensuring the StreamPark service account has the minimum necessary permissions on the host system.
• Implement a Web Application Firewall (WAF) with rules designed to inspect and block malicious job submission payloads.

Public Exploit Available: false

Due to the high severity (CVSS 7.3) of this vulnerability and its potential for complete system compromise, immediate remediation is critical. Although CVE-2025-30001 is not currently listed on the CISA KEV catalog, its impact on data processing infrastructure is significant. We strongly recommend that all organizations using Apache StreamPark treat this as a critical priority and apply the vendor-supplied security patches on an emergency basis to mitigate the risk of exploitation.
