CVE-2026-67621

Flowise through 3.1.4 contains a missing authorization vulnerability that allows authenticated workspace members to perform unauthorized document store operations by accessing unprotected mutation endpoints. Attackers holding only view-level permissions can send direct HTTP requests to the upsert and refresh document store routes to trigger document ingestion, refresh vector database contents, consume embedding API credits, and modify knowledge bases used by downstream chatflows.

Summary		(es) Flowise a través de 3.1.4 contiene una vulnerabilidad de autorización faltante que permite a los miembros autenticados del espacio de trabajo realizar operaciones no autorizadas en el almacén de documentos al acceder a puntos finales de mutación no protegidos. Los atacantes que poseen solo permisos de nivel de vista pueden enviar solicitudes HTTP directas a las rutas de upsert y refresh del almacén de documentos para activar la ingesta de documentos, refrescar el contenido de la base de datos vectorial, consumir créditos de la API de incrustación y modificar las bases de conocimiento utilizadas por los chatflows posteriores.
