  "title": "Denial of service in multer asynchronous file filtering",
  "summary": "multer versions 2.0.0 through 2.4.x can terminate a Node.js process during multipart uploads. An attacker able to cancel an upload while an asynchronous fileFilter is awaiting completion may trigger the failure; applications using synchronous filtering are not affected.",
