Vulnerability details
The vulnerability allows a remote user to disclose sensitive information.
The vulnerability exists due to generation of error messages containing sensitive information in REST API error handlers in server/models/users.js and server/models/boards.js when handling crafted API requests that trigger catch blocks. A remote user can send a specially crafted request to disclose sensitive information.
Error conditions are returned as HTTP 200 responses with serialized error objects, and non-serializable errors may produce a corrupted {\"_id\":{}} response that can act as an error oracle.
