CVE-2026-73487

Flowise before 3.1.3 contains a regex-based Python code validator bypass in CSV and Airtable Agent nodes that allows unauthenticated attackers to inject malicious code via prompt injection. Attackers can exploit unblocked pandas functions like pd.read_json() to exfiltrate datasets, perform SSRF against internal services, or achieve code execution through the unauthenticated prediction API.

Summary		(es) Flowise anterior a la versión 3.1.3 contiene una omisión del validador de código Python basado en expresiones regulares en los nodos de agente CSV y Airtable que permite a atacantes no autenticados inyectar código malicioso mediante inyección de prompts. Los atacantes pueden explotar funciones de pandas no bloqueadas como pd.read_json() para exfiltrar conjuntos de datos, realizar SSRF contra servicios internos o lograr la ejecución de código a través de la API de predicción no autenticada.
