      "value": "Flowise before 3.0.6 contains an arbitrary file access vulnerability due to missing validation that the chatflowId and chatId parameters are UUIDs or numbers in file handling operations. By supplying a path-traversal value (e.g., '../../../../../tmp') as the chatflow id, an unauthenticated attacker can use the /api/v1/chatflows endpoint (via addBase64FilesToStorage) to write arbitrary files, and the /api/v1/get-upload-file and /api/v1/openai-assistants-file/download endpoints (via streamStorageFile) to read arbitrary files. Arbitrary file write may lead to remote code execution."

      "value": "Flowise antes de la versión 3.0.6 (versiones afectadas 2.2.8 y anteriores) contiene una vulnerabilidad de acceso arbitrario a archivos debido a la falta de validación de que los parámetros chatflowId y chatId son UUIDs o números en las operaciones de manejo de archivos. Al proporcionar un valor de path-traversal (por ejemplo, '.. / .. / .. / .. / ../tmp') como el ID del chatflow, un atacante no autenticado puede usar el endpoint /api/v1/chatflows (a través de addBase64FilesToStorage) para escribir archivos arbitrarios, y los endpoints /api/v1/get-upload-file y /api/v1/openai-assistants-file/download (a través de streamStorageFile) para leer archivos arbitrarios. La escritura arbitraria de archivos puede conducir a la ejecución remota de código."
