Summary

Vorota-ai nmap-mcp through commit 3636afa contains an improper allowlist validation flaw in the scan_vulnerabilities tool. The permissive allowlist (CWE-183) lets callers pass blocked NSE script categories such as exploit, dos, brute, or intrusive to nmap --script. A local user with low privileges, or a prompt-injected agent, can run intrusive, brute-force, exploit, or denial-of-service scripts against scan targets.
