CVE-2025-68422 is an authorization bypass vulnerability classified under CWE-863 (Incorrect Authorization) found in Elastic Kibana versions 7.0.0 through 9.2.0. The flaw allows an authenticated user who lacks the 'live queries - read' permission to circumvent intended access controls by sending specially crafted HTTP requests. This results in unauthorized disclosure of live query lists, which could contain sensitive operational or investigative data. The vulnerability stems from improper enforcement of permission checks within Kibana's API endpoints handling live query data. Exploitation requires valid user credentials but no additional user interaction, and the attack can be performed remotely over the network. The CVSS v3.1 score is 4.3 (medium), reflecting low attack complexity and network vector but limited impact confined to confidentiality. No integrity or availability impacts are noted. No patches or exploits are currently publicly available, but the vulnerability is officially published and should be addressed promptly. This issue highlights the importance of strict authorization checks in multi-tenant or role-based access control environments like Kibana, which is widely used for data visualization and monitoring in enterprise environments.

For European organizations, the primary impact of CVE-2025-68422 is the unauthorized disclosure of live query information within Kibana dashboards. This could expose sensitive operational data, potentially revealing internal monitoring activities, investigative queries, or security-related information. While the vulnerability does not allow modification or disruption of services, the confidentiality breach could aid attackers in reconnaissance or lateral movement within networks. Organizations in regulated sectors such as finance, healthcare, and critical infrastructure may face compliance risks if sensitive data is exposed. Additionally, exposure of live queries could indirectly reveal security monitoring strategies, weakening defensive postures. Given Kibana's widespread use in European enterprises for log analysis and security monitoring, this vulnerability could affect many organizations if exploited. However, the requirement for authenticated access limits the attack surface to insiders or compromised accounts. The absence of known exploits reduces immediate risk but does not eliminate the need for vigilance.

1. Monitor Elastic's official channels for patches addressing CVE-2025-68422 and apply updates promptly once available. 2. Review and tighten Kibana user permissions, ensuring the principle of least privilege is enforced, particularly restricting 'live queries - read' permissions to only necessary users. 3. Implement strong authentication mechanisms such as multi-factor authentication (MFA) to reduce the risk of credential compromise. 4. Audit existing user accounts and remove or disable inactive or unnecessary accounts to minimize potential attackers with valid credentials. 5. Employ network segmentation and firewall rules to limit access to Kibana interfaces to trusted networks and users. 6. Enable detailed logging and monitoring of Kibana access and API calls to detect anomalous or unauthorized activities related to live queries. 7. Consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block suspicious crafted HTTP requests targeting Kibana APIs. 8. Educate administrators and users about the risks of privilege escalation and encourage prompt reporting of suspicious behavior. These steps go beyond generic advice by focusing on access control hardening, proactive monitoring, and network-level protections tailored to Kibana environments.
