Attack-Flow Graph

Executive Summary

This vulnerability is a Cross-site Scripting (XSS) issue where an authenticated user can embed malicious scripts into web content generated by the Vega application. This happens because the input is not properly neutralized during web page generation, allowing the malicious script to be served to other users' web browsers. It bypasses previous XSS mitigations in Vega.

Impact Analysis

The vulnerability can allow attackers to execute malicious scripts in the context of other users' browsers, potentially leading to theft of sensitive information, session hijacking, or unauthorized actions performed on behalf of users. This can compromise the confidentiality and integrity of user data.
