multer vulnerable to Denial of Service via file descriptor leak on aborted uploads

Impact A vulnerability in multer 2.2.0 allows an attacker to trigger a Denial of Service DoS by aborting or truncating multipart uploads. When using diskStorage, the destination write stream is not closed if the upload is aborted before it finishes, so each failed request leaks an open file...
