CVE-2026-33053

Langflow is a tool for building and deploying AI-powered agents and workflows. In versions prior to 1.9.0, the delete_api_key_route() endpoint accepts an api_key_id path parameter and deletes it with only a generic authentication check (get_current_active_user dependency). However, the delete_api_key() CRUD function does NOT verify that the API key belongs to the current user before deletion.

Summary		(es) Langflow es una herramienta para construir y desplegar agentes y flujos de trabajo impulsados por IA. En versiones anteriores a la 1.9.0, el endpoint delete_api_key_route() acepta un parámetro de ruta api_key_id y lo elimina con solo una verificación de autenticación genérica (dependencia get_current_active_user). Sin embargo, la función CRUD delete_api_key() NO verifica que la clave API pertenezca al usuario actual antes de la eliminación.
