CVE-2026-54149
Full vulnerability record from the local CVENow database.
Description
MaxKB is an open-source AI assistant for enterprise. Prior to 2.10.0-lts, MaxKB tool import functionality in apps/tools/serializers/tool.py and MCP referencing mode in apps/application/chat_pipeline/step/chat_step/impl/base_chat_step.py do not consistently validate MCP transport type, allowing an authenticated user to import a .tool file containing stdio transport with malicious commands and trigger the configuration through an AI Chat node so MultiServerMCPClient executes arbitrary system commands. This issue is fixed in version 2.10.0-lts.

Antes de 2.10.0-lts, la funcionalidad de importación de herramientas de MaxKB en apps/tools/serializers/tool.py y el modo de referencia de MCP en apps/application/chat_pipeline/step/chat_step/impl/base_chat_step.py no validan consistentemente el tipo de transporte MCP, permitiendo a un usuario autenticado importar un archivo .tool que contiene transporte stdio con comandos maliciosos y activar la configuración a través de un nodo de chat de IA de modo que MultiServerMCPClient ejecute comandos de sistema arbitrarios. Este problema está corregido en la versión 2.10.0-lts."
