      "value": "Langflow is a tool for building and deploying AI-powered agents and workflows. Prior to 1.10.0, the \"Shareable Playground\" (or \"Public Flows\" in code) contains a potential arbitrary file-read vulnerability, depending on the exact flow configuration used. By making a flow public, public execution of the flow is allowed. The execution request can contain a list of files that gets read by Langflow and fed into the LLM. The files path can be any path supported by the storage - it can be either a local file or S3 path if supported by the local configuration This vulnerability is fixed in 1.10.0."

Antes de 1.10.0, el ’Shareable Playground’ (o ’Public Flows’ en el código) contiene una potencial vulnerabilidad de lectura arbitraria de archivos, dependiendo de la configuración exacta del flujo utilizada. Al hacer público un flujo, se permite la ejecución pública del flujo. La solicitud de ejecución puede contener una lista de archivos que son leídos por Langflow y alimentados al LLM. La ruta de los archivos puede ser cualquier ruta compatible con el almacenamiento - puede ser un archivo local o una ruta S3 si es compatible con la configuración local. Esta vulnerabilidad está corregida en 1.10.0."
