CVE-2025-12245 Details
Description
A vulnerability was identified in chatwoot up to 4.7.0. This vulnerability affects the function initPostMessageCommunication of the file app/javascript/sdk/IFrameHelper.js of the component Widget. The manipulation of the argument baseUrl leads to origin validation error. Remote exploitation of the attack is possible. The vendor was contacted early about this disclosure but did not respond in any way.
A vulnerability exists in Chatwoot versions through 4.7.0, specifically within the widget component's IFrameHelper.js file. The issue arises in the initPostMessageCommunication function, where the baseUrl argument is not properly validated. This origin validation error allows for remote exploitation, enabling attackers to hijack the cw_conversation token. This token theft could lead to unauthorized access to a victim's conversation history, potentially exposing sensitive information.
To address this vulnerability, Chatwoot developers should implement origin validation for postMessage events, ensuring that only messages from trusted domains are processed. Additionally, sensitive tokens like cw_conversation should not be exposed in popup URLs.
