AI-suggested
Until a fix is available, restrict access to the affected endpoints to trusted users and monitor for suspicious activity involving message UUIDs. Implement additional owner checks in the application code to prevent unauthorized access.
Description
langchain4j-aideepin versions up to 3.32.0 have an authorization bypass vulnerability in the CharacterMessageController. Authenticated users can exploit missing ownership checks to access other users' message references by supplying another user's message UUID to certain endpoints. This allows unauthorized retrieval of knowledge-base chunks, long-term memory text, and knowledge-graph data.
