CVE-2026-75011Public exploitNetwork attack vector

Authenticated command injection via shell-built tshark calls

Published Aug 17, 2026 · Updated Aug 19, 2026

Command injection in kylecui NetForensicMCP 2.1.0 allows remote authenticated users to execute OS commands via crafted tool arguments. In index.js, capture_packets, extract_stream_content, and get_stream_info build tshark shell command strings and pass unsanitized interface and protocol values to child_process.exec via execAsync. Reachability requires access to invoke MCP tools, but any caller that can trigger those tools, including a manipulated MCP client on Windows, can run commands with the server process's privileges.
