What is CVE-2025-68385?

CVE-2025-68385 is a cross-site scripting (XSS) vulnerability identified in Vega, a product developed by Elastic that is designed for data visualization and analysis. This vulnerability arises from improper handling of user input during web page generation, allowing an authenticated user to inject malicious scripts. When such scripts are executed in the browsers of other users accessing the affected content, it can lead to serious consequences, including data theft and session hijacking. The XSS flaw is notable because it bypasses previously implemented XSS mitigations in Vega, highlighting potential weaknesses in the overall security design. Organizations utilizing Vega for their data presentation and analysis could face reputational damage and financial losses due to compromised user data and system integrity.

Potential impacts of CVE-2025-68385

  1. Data Breach Risks: The XSS vulnerability enables attackers to embed malicious scripts that can steal sensitive user information, including login credentials and personal data, leading to unauthorized access and potential data breaches.

  2. Reputation Damage: Organizations affected by this vulnerability risk losing customer trust and credibility, as users may feel their information is not secure. This can have long-lasting effects on customer relationships and brand loyalty.

  3. Operational Disruption: Exploitation of this vulnerability could lead to operational disruptions, such as unauthorized access to internal systems or the execution of malicious actions, resulting in downtime and the need for extensive remediation efforts.
