Background
fomantic-ui is an npm package that provides a user interface framework for building responsive and accessible websites. It offers a wide range of components and styling options to enhance the visual appeal and functionality of web applications. However, versions of fomantic-ui are vulnerable to Cross-Site Scripting (XSS) attacks. This vulnerability arises due to the lack of output encoding on the selection dropdowns, allowing user input to be executed instead of being displayed as plain text.
Vulnerability Detail
The Cross-Site Scripting vulnerability in fomantic-ui can be exploited by an attacker to inject malicious scripts into web pages viewed by unsuspecting users. This can lead to various harmful consequences, such as stealing sensitive information, performing unauthorized actions on behalf of the user, or manipulating the appearance and behavior of the website. The lack of output encoding on the selection dropdowns enables the execution of user-supplied code, making it crucial to address this vulnerability promptly.
