Nezha from 2.1.0 before 2.3.15 contains a host header injection vulnerability in mintTransferTool that builds fs.download_url and fs.upload_url transfer URLs from the unvalidated Host header. Attackers who control the Host header seen on a victim's MCP request can redirect file uploads or capture one-time download tokens and replay them to exfiltrate files.
