Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

lightrag-hku versions before 1.5.5 pass raw Python exception messages into HTTP error responses across many API route handlers. A network-reachable client, without credentials under the default configuration, can trigger these errors and read details such as server filesystem paths, database host, port and user, LLM provider details, and library internals. Upgrade to lightrag-hku 1.5.5 or later.
