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 Operator Chat Name Field Triggers on Chat Owner Transfer Functionality on Live Helper Chat.
## Reproduction Steps:
1. Log in as an operator.
2. Navigate to your operator settings page.
3. In the **Name** field, enter the following payload:
``` "><img src="x" onerror="prompt(1);"> ```
4. Save the changes.
5. Initiate a chat with a visitor.
6. Transfer the chat to another operator — the XSS payload executes in the receiving operator’s chat interface.
