## How to fix

- Fixed in 2.3.6.2

## Technical details

The vulnerability is a reflected cross-site scripting (XSS) flaw in the Web UI that fails to properly neutralize user input before rendering it to the browser (CWE-79). The attack requires user interaction (clicking a malicious link) but no authentication, and can affect other users in the same security context. An attacker gains the ability to execute arbitrary JavaScript in victims' browsers and potentially exfiltrate session credentials or modify application behavior.
