    A stored cross-site scripting (XSS) vulnerability in Live Helper Chat
    version ≤ 4.61 allows attackers to execute arbitrary JavaScript by
    injecting a crafted payload into the Telegram Bot Username parameter. This

    user views or edits the Telegram Bot Username.
    
    
    ## Reproduction Steps:
    
    1. Log in as an operator user in Live Helper Chat.
    2. Navigate to `Settings > Live Help Configuration > Telegram Bot`.

    ```
       "><img src="x" onerror="prompt(1);">
    ```
    4. Save the settings.
    5. Revisit the Telegram configuration panel and — the payload will execute.
