CVE-2025-60536 is a vulnerability identified in the kafka-ui application, specifically versions 0.6.0 through 0.7.2. The flaw exists in the 'Configure New Cluster' interface, where an attacker can upload a crafted configuration file that triggers a Denial of Service (DoS) condition. Kafka-ui is a user interface tool used to manage Apache Kafka clusters, which are widely used for real-time data streaming and processing. The vulnerability allows an attacker to disrupt the availability of the kafka-ui service by exploiting improper handling or validation of configuration files during cluster setup. Since the vulnerability does not require authentication or user interaction, it can be exploited remotely if the interface is exposed to untrusted networks. The lack of a CVSS score and absence of known exploits in the wild suggest it is a newly published issue, with no official patches currently available. However, the potential impact on availability is significant, as denial of service in kafka-ui could hinder cluster management and monitoring, affecting dependent applications and services. The vulnerability likely stems from insufficient input validation or error handling when processing configuration files, which could cause the application to crash or become unresponsive. This issue highlights the importance of securing management interfaces and validating all user inputs, especially in tools that control critical infrastructure components like Kafka clusters.

The primary impact of CVE-2025-60536 is on the availability of kafka-ui, which could lead to denial of service conditions. For European organizations, especially those relying heavily on Apache Kafka for critical data streaming, analytics, and real-time processing, this disruption could delay or halt operational workflows, impacting business continuity. Industries such as finance, telecommunications, manufacturing, and public services that use Kafka for event-driven architectures may experience degraded service or outages. The inability to configure or manage Kafka clusters effectively could also increase operational risks and recovery times. Since kafka-ui is often used as a management and monitoring tool, its unavailability could reduce visibility into cluster health and complicate incident response. Although the vulnerability does not directly compromise confidentiality or integrity, the resulting service disruption can have cascading effects on dependent systems and applications. The lack of authentication requirements for exploitation increases the risk, particularly if the kafka-ui interface is exposed beyond trusted internal networks. Organizations with strict regulatory requirements around uptime and service availability, such as those governed by GDPR or critical infrastructure directives, may face compliance challenges if this vulnerability is exploited.

To mitigate CVE-2025-60536, organizations should first restrict access to the kafka-ui 'Configure New Cluster' interface by implementing network segmentation and firewall rules to limit exposure to trusted administrators only. Employ VPNs or zero-trust network access solutions to secure remote connections. Implement strict input validation and sanitization for configuration files uploaded through the interface, ensuring only well-formed and authorized configurations are accepted. Monitor kafka-ui logs and system behavior for signs of abnormal activity or crashes related to configuration uploads. If possible, upgrade kafka-ui to versions beyond 0.7.2 once patches addressing this vulnerability are released. In the interim, consider disabling the cluster configuration upload feature or replacing it with manual configuration methods to reduce attack surface. Conduct regular security assessments and penetration testing focused on management interfaces. Establish incident response procedures to quickly recover from potential DoS events affecting kafka-ui. Finally, maintain awareness of updates from kafka-ui developers and the security community for any new advisories or exploit reports.
