A vulnerability of authorization bypass through user-controlled key in the 'console-survey/api/v1/answer/{EVENTID}/{TIMESTAMP}/' endpoint.

This publicly exposed data may include IDs, private URLs, private messages, internal references, or other sensitive information that should only be exposed to authenticated users. In addition, the leaked content could be exploited to facilitate other malicious activities, such as reconnaissance for lateral movement, exploitation of related systems, or unauthorised access to internal applications referenced in the content of chat messages.
