Description
langchain4j-aideepin through 3.32.0 contains an insecure direct object reference vulnerability in CharacterMessageController that allows authenticated users to access other users' message references due to missing owner checks. Attackers can supply another user's message uuid to the knowledge-embedding-ref, memory-embedding-ref, or graph-ref endpoints to retrieve knowledge-base chunks, long-term memory text, and knowledge-graph data.
