Langroid: handle_message() executes user-supplied tool JSON without sender verification

Published Jul 9, 2026 · Updated Jul 10, 2026 · Assigned by GitHub_M

Description

Langroid is a framework for building large-language-model-powered applications. Prior to version 0.65.3, a Langroid application exposing a chat interface to untrusted users may allow direct tool invocation via raw JSON payloads, even when tools are registered with `use=False, handle=True`. Version 0.65.3 fixes the issue.
