CVE-2025-67744

DeepChat is an open-source artificial intelligence agent platform that unifies models, tools, and agents. Prior to version 0.5.3, a security vulnerability exists in the Mermaid diagram rendering component that allows arbitrary JavaScript execution. Due to the exposure of the Electron IPC renderer to the DOM, this Cross-Site Scripting (XSS) flaw escalates to full Remote Code Execution (RCE), allowing an attacker to execute arbitrary system commands. Two concurrent issues, unsafe Mermaid configuration and an exposed IPC interface, cause this issue. Version 0.5.3 contains a patch.

Summary		(es) DeepChat es una plataforma de agentes de inteligencia artificial de código abierto que unifica modelos, herramientas y agentes. Antes de la versión 0.5.3, existe una vulnerabilidad de seguridad en el componente de renderizado de diagramas Mermaid que permite la ejecución arbitraria de JavaScript. Debido a la exposición del renderizador IPC de Electron al DOM, este fallo de cross-site scripting (XSS) escala a ejecución remota de código (RCE) completa, permitiendo a un atacante ejecutar comandos de sistema arbitrarios. Dos problemas concurrentes, una configuración insegura de Mermaid y una interfaz IPC expuesta, causan este problema. La versión 0.5.3 contiene un parche.
