khoj-ai khoj Conversation Sharing api_chat.py authorization

A flaw has been found in khoj-ai khoj up to 2.0.0-beta.28. This impacts an unknown function of the file src/khoj/routers/api_chat.py of the component Conversation Sharing Handler. This manipulation of the argument conversation.agent causes incorrect authorization. Remote exploitation of the attack is possible. The exploit has been published and may be used. The pull request to fix this issue awaits acceptance.
