Background
Vega is a visualization grammar that provides a declarative format for creating, saving, and sharing interactive visualization designs. It is available as an npm package. Vega allows users to create visualizations using a JSON-based syntax. It is widely used for data visualization purposes in various applications.
However, Vega versions prior to 5.17.3 are vulnerable to a cross-site scripting (XSS) attack. This vulnerability exists in Vega expressions, which are used to define visualizations. An attacker can exploit this vulnerability by crafting a malicious Vega expression, allowing them to execute arbitrary JavaScript code on a victim's machine. This can lead to unauthorized access, data theft, or other malicious activities.
Vulnerability Detail
The XSS vulnerability in Vega arises due to insufficient input sanitization in Vega expressions. When a specially crafted Vega expression is processed, the JavaScript code within it is executed on the victim's machine. This can be exploited by an attacker to perform various malicious actions, such as stealing sensitive information, modifying content, or performing unauthorized actions on behalf of the victim.
The vulnerability has a CVSS score of 8.7, indicating a high severity level. It is crucial to address this vulnerability promptly to prevent potential security breaches.
