Name of the Vulnerable Software and Affected Versions Readdle Documents app versions prior to 6.9.7

Description An issue was discovered in the Readdle Documents app, where the application's file-transfer web server allows for cross-origin requests from any domain, and the WebSocket server lacks authorization control. This allows any web site to execute JavaScript code that accesses a user's data via cross-origin requests.

Recommendations For versions prior to 6.9.7, update to version 6.9.7 or later to resolve the issue. As a temporary workaround, consider restricting access to the file-transfer web server and WebSocket server to minimize the risk of exploitation. Avoid using the Readdle Documents app until the issue is resolved.
