This vulnerability allows an attacker to exploit the `vlSelectionTuples` function in Vega, which can lead to cross-site scripting (XSS). As the vulnerability has a CVSS score of 6.9, it falls into the medium severity category. Organizations should be aware of the potential risks and prioritize remediation for affected versions.
Risk to organizations includes unauthorized JavaScript execution in the context of the user, potentially leading to data theft, session hijacking, or other malicious actions. The vulnerability is known to exist in versions prior to 5.26.0 of Vega and 5.4.2 of Vega-selections.
As of now, the exploitation status is deferred, meaning there is no confirmed public exploit available. However, organizations should not delay in applying patches to mitigate the risk.
Organizations should prioritize patching immediately.
Vulnerability Details
Vega is a visualization grammar allowing for interactive visualization design. The vulnerability arises from the `vlSelectionTuples` function, which can invoke JavaScript functions controlled by an attacker. This can allow execution of arbitrary JavaScript code, leading to cross-site scripting vulnerabilities.
The CVSS score of 6.9 indicates a medium severity, with low attack complexity and no privileges required to exploit the vulnerability. The vulnerability was published on February 14, 2025.
Technical Analysis
The root cause of the vulnerability is the ability of the `vlSelectionTuples` function to call multiple functions, including those with attacker-controlled arguments. This allows an attacker to execute arbitrary JavaScript code.
The attack vector is network-based, requiring no user interaction, and operates with low attack complexity. The impacts are minimal concerning confidentiality, integrity, and availability.
Risk & Impact Analysis
The risk to organizations includes potential unauthorized access to user data and session hijacking. If exploited, this vulnerability could have significant impacts, particularly for applications relying on Vega for data visualization.
Given the potential for exploitation, organizations should assess the likelihood of being targeted and the potential blast radius. With the CVSS score indicating a medium severity, organizations should address this vulnerability in their priority patch cycle.

Affected Versions
This vulnerability affects versions of Vega prior to 5.26.0 and Vega-selections prior to 5.4.2. Organizations should ensure that they are running updated versions to mitigate the risk associated with this vulnerability.
Mitigation & Remediation
To remediate this vulnerability, organizations should update to Vega version 5.26.0 or later and Vega-selections version 5.4.2 or later.
If a patch is not immediately available, organizations should consider implementing additional security controls, including input validation and sanitization of user inputs, to prevent exploitation of this vulnerability.
Organizations should validate remediation through penetration testing to ensure that the vulnerabilities have been effectively addressed.
Detection Guidance
Organizations should monitor application logs for unusual JavaScript execution patterns that may indicate exploitation attempts. Additionally, keep an eye on user input fields that interact with the Vega library.
