Description
A stored cross-site scripting (XSS) vulnerability in the HTTP Proxy field within the Datacenter configuration panel of Proxmox Virtual Environment (PVE) 8.4 allows an authenticated user to inject malicious input. The input is stored and executed in the context of other users' browsers when they view the affected configuration page. This can lead to arbitrary JavaScript execution.
