Descripción
*** Pendiente de traducción *** Cinnamon&#39;s Kotaemon (all versions up to and including v0.12.0) multi-user chat interface contains multiple vulnerabilities due to incorrect authorization and improper access controls. There are four handler methods in `libs/ktem/ktem/pages/chat/control.py` that load a Conversation record by its ID without comparing the requester&#39;s `user_id` to the conversation&#39;s owner `Conversation.user`. This allows any authenticated user to perform the following actions:<br />
1. Read other user&#39;s chat transcripts, RAG retrieval history, AI-generated plots, and chat suggestions.<br />
2. Permanently delete another user&#39;s conversation.<br />
3. Rename another user&#39;s conversation.<br />
4. Overwrite another user&#39;s conversation&#39;s chat suggestion list.
