Submit #781810: 1Panel-dev MaxKB <= v2.2.1 Stored XSSinfo

Title1Panel-dev MaxKB <= v2.2.1 Stored XSS
DescriptionMaxkb is vulnerable to Stored Cross-Site Scripting (XSS) due to a lack of HTML escaping when processing application names and icons. An authenticated user can create an application with a malicious payload in the application name. When any user visits the public chat interface (/ui/chat/{access_token}), StaticHeadersMiddleware performs unescaped string replacement to inject the application data directly into the HTML response. This allows the attacker to break out of the <title> tag and execute arbitrary JavaScript in the victim's browser context.
