Elastic has issued critical security updates to address a cross-site scripting (XSS) vulnerability in multiple versions of Kibana. This vulnerability, identified as CVE-2025-68385, permits authenticated attackers to inject malicious scripts into web pages served to other users.
The vulnerability arises from improper input neutralization during web page generation, specifically within Kibana's Vega visualization component. Attackers can bypass existing security measures, allowing malicious scripts to execute in the browsers of users viewing the affected content. This can compromise sensitive data or session information.
Classified under CWE-79 (Cross-site Scripting), the vulnerability affects the entire Vega method implementation. Although the attacker must be authenticated, the impact is significant as it can affect multiple users using the same Kibana instance.
The affected versions include all releases of the 7.x branch. Within the 8.x series, versions from 8.0.0 to 8.19.8 are vulnerable. The 9.x branch includes vulnerabilities in versions 9.0.0 to 9.1.8 and 9.2.0 to 9.2.2.
Elastic has issued critical security updates to address a cross-site scripting (XSS) vulnerability in multiple versions of Kibana.
Elastic has rated this vulnerability with a CVSSv3.1 score of 7.2 (High), noting the network-based attack vector, low complexity for exploitation, and lack of required user interaction beyond initial authentication. The vulnerability could compromise data confidentiality and integrity across multiple systems.
To mitigate this issue, Elastic has released patched versions: Kibana 8.19.9, 9.1.9, and 9.2.3. These updates include fixes to ensure proper neutralization of malicious input in Vega visualizations and restore XSS protections.
Organizations are advised to upgrade to the patched versions immediately. Security teams should prioritize updating Kibana deployments and review instances for any suspicious visualizations or content generated by authenticated users. Implementing network segmentation and restricting Kibana access to trusted users can offer additional protection during the upgrade process.
