CVE-2026-8481

IBM Langflow OSS 1.0.0 through 1.10.0 contain a critical remote code execution vulnerability in the code validation API endpoint. The POST /api/v1/validate/code endpoint accepts user-supplied Python code and executes it directly using Python's built-in exec() function without sandboxing, input validation, or privilege restrictions, enabling any authenticated user to execute arbitrary system commands with the full privileges of the Langflow server process.

Summary		(es) IBM Langflow OSS 1.0.0 hasta 1.10.0 contienen una crítica vulnerabilidad de ejecución remota de código en el endpoint de la API de validación de código. El endpoint POST /api/v1/validate/code acepta código Python suministrado por el usuario y lo ejecuta directamente usando la función exec() incorporada de Python sin sandboxing, validación de entrada o restricciones de privilegios, permitiendo a cualquier usuario autenticado ejecutar comandos de sistema arbitrarios con los privilegios completos del proceso del servidor Langflow.
