Flowise – Arbitrary File Write to Remote Code Execution via document-store API_CVE-2025-71338

{
    "lastseen": "",
    "description": "Flowise contains a path traversal vulnerability in the /api/v1/document-store/loader/process endpoint that allows unauthenticated attackers to write arbitrary files to the filesystem. Attackers can exploit unsanitized fileName parameters with ../ sequences to overwrite critical files like package.json and achieve remote code execution when the application restarts.",
