LangChat through commit 2a6285a contains a missing authentication vulnerability that allows unauthenticated remote attackers to access REST controllers because no Sa-Token interceptor is registered. Attackers can query /api/v1/auth/users to read plaintext passwords, retrieve LLM provider API keys, create super-admin accounts, and modify or delete data.
