CVE-2025-62714 is an authentication bypass vulnerability categorized under CWE-862 affecting the Karmada Dashboard, a web-based control panel for managing multiple Kubernetes clusters. Versions prior to 0.2.0 do not enforce authentication on backend API endpoints such as /api/v1/secret and /api/v1/service. While the dashboard's web UI requires a valid JWT token, the API endpoints themselves lack any authentication checks, allowing unauthenticated users with network access to directly query sensitive cluster resources. This design flaw exposes critical data including Kubernetes Secrets and Services, which could be leveraged for further attacks or unauthorized access within the cluster environment. The vulnerability is remotely exploitable without any privileges or user interaction, making it highly dangerous in exposed network environments. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N) indicates network attack vector, low complexity, no authentication or user interaction required, and a high impact on confidentiality. No patches or exploits in the wild are currently reported, but the risk remains significant for organizations running vulnerable versions. The vulnerability highlights a critical security oversight in API design where authentication enforcement was inconsistently applied between the UI and backend services.

The primary impact of CVE-2025-62714 is unauthorized disclosure of sensitive Kubernetes cluster information, including Secrets and Services, which can compromise the confidentiality of credentials, configuration data, and service endpoints. For European organizations, this can lead to data breaches, unauthorized lateral movement within cloud or on-premises infrastructure, and potential disruption of multi-cluster operations. The exposure of Secrets can facilitate privilege escalation or unauthorized access to critical systems, increasing the risk of ransomware, data theft, or sabotage. Given the multi-cluster management context, the compromise of one dashboard instance could cascade into multiple clusters, amplifying the impact. Organizations in Europe with cloud-native deployments, especially those managing hybrid or multi-cloud Kubernetes environments, face heightened risk. The vulnerability could also undermine compliance with GDPR and other data protection regulations due to unauthorized access to sensitive data. The lack of authentication requirement and ease of exploitation make this a critical threat that could be exploited by internal or external attackers with network access to the dashboard service.

1. Upgrade Karmada Dashboard to version 0.2.0 or later where authentication enforcement on API endpoints is implemented. 2. Restrict network access to the Karmada Dashboard service using network segmentation, firewalls, or VPNs to limit exposure to trusted users and systems only. 3. Implement strong network-level access controls and monitoring to detect and block unauthorized API requests. 4. Use Kubernetes Role-Based Access Control (RBAC) and secrets management best practices to minimize the impact of any potential data exposure. 5. Regularly audit and monitor API access logs for unusual or unauthorized activity targeting the dashboard endpoints. 6. Consider deploying Web Application Firewalls (WAFs) or API gateways that enforce authentication and rate limiting on dashboard API traffic. 7. Educate DevOps and security teams about the vulnerability and ensure rapid patch management processes are in place for critical infrastructure components. 8. If upgrading immediately is not feasible, temporarily disable or isolate the dashboard API endpoints until a patch can be applied.
