| عنوان | Chatwoot * Origin Validation Error |
|---|
| الوصف | An unrestricted postMessage vulnerability in Chatwoot widget integrations allows attackers to hijack the cw_conversation token via a crafted message. With one click, an attacker can steal this token and retrieve the full conversation history of a victim, potentially exposing sensitive information. The embedded widget listens to postMessage events without validating the origin of the sender.
A malicious site can send a forged postMessage with the event popoutChatWindow, specifying a malicious baseUrl. Without validating the message origin, the widget directly calls popoutChatWindow with the supplied baseUrl. This function builds a popup URL that includes the cw_conversation cookie value as a parameter and opens it. The attacker can intercept the popup into their own controlled window and capture the cw_conversation token directly from the request URL. |
