| Title | 1Panel-dev MaxKB <= v2.6.1 Stored XSS |
|---|
| Description | A Stored Cross-Site Scripting (XSS) vulnerability exists in MaxKB. Authenticated users can inject malicious JavaScript into the application name or icon fields when creating an application. When a victim visits the public chat interface (/ui/chat/{access_token}), the ChatHeadersMiddleware retrieves the application data and directly inserts the unescaped application name and icon into the HTML response via string replacement. This allows an attacker to execute arbitrary JavaScript in the victim's browser context.
