This manipulation of the argument Name causes cross site scripting. Remote exploitation of the attack is possible. Upgrading to version 2.8.0 is capable of addressing this issue.

The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product.
A stored cross-site scripting vulnerability has been identified in 1Panel-dev MaxKB versions through 2.6.1. The issue resides in the ChatHeadersMiddleware component, specifically within the file apps/common/middleware/chat_headers_middleware.py. This vulnerability allows authenticated users to inject malicious JavaScript into the application name or icon fields when creating an application. The injected script is executed when a victim accesses the public chat interface, as the middleware unescapes and inserts the application data directly into the HTML response. Remote exploitation is possible, requiring user interaction.
Users are advised to upgrade to MaxKB version 2.8.0, which addresses this vulnerability.
