GHSA-gjgq-w2m6-wr5q: Langroid: handle_message() executes user-supplied tool JSON without sender verification
Summary
Langroid has a security flaw where tools registered with `use=False, handle=True` (meant to prevent the AI from calling them) can still be invoked directly by users sending raw JSON chat messages, because the message-handling code doesn't verify whether the message came from a user or the AI. This could allow unauthorized access to sensitive operations like file access or database queries depending on which tools are enabled.
