CVE-2026-73485

Flowise before 3.1.3 contains a code injection vulnerability in the Airtable Agent node that allows unauthenticated attackers to execute arbitrary Python code by bypassing the pythonCodeValidator blocklist through obfuscation techniques. Attackers can send crafted prompts to a chatflow using the Airtable Agent node to inject malicious Python code that executes in an unsandboxed pyodide environment with full access to the host operating system.

Summary		(es) Flowise anterior a la versión 3.1.3 contiene una vulnerabilidad de inyección de código en el nodo Airtable Agent que permite a atacantes no autenticados ejecutar código Python arbitrario al eludir la lista negra de pythonCodeValidator mediante técnicas de ofuscación. Los atacantes pueden enviar prompts manipulados a un chatflow utilizando el nodo Airtable Agent para inyectar código Python malicioso que se ejecuta en un entorno pyodide sin sandbox con acceso total al sistema operativo anfitrión.
