    Cross-site Scripting (XSS)

    home-assistant-js-websocket is a Home Assistant websocket client

    Affected versions of this package are vulnerable to Cross-site Scripting (XSS) via the state parameter in the WebSocket authentication logic. An attacker can spoof WebSocket responses and execute this vulnerability by crafting a malicious link with a modified state parameter that redirects the frontend to an alternative WebSocket backend. This is only exploitable if the attacker can persuade the victim to click on a malicious link. Additionally, the ability to iframe the site from other origins can make the attack more covert, as a malicious website could hide the attack in the background

    How to fix Cross-site Scripting (XSS)?

    Upgrade home-assistant-js-websocket to version 8.2.0 or higher.
