Nuclei — Template-Based Vulnerability Scanner

Nuclei — Template-Based Vulnerability Scanner

Nuclei is a community-powered, template-based vulnerability scanner by ProjectDiscovery. Its YAML template engine makes it trivially extensible — write a template once, scan thousands of targets. The community maintains 9,000+ templates covering CVEs, misconfigurations, exposed panels, default credentials, and AI/LLM-specific checks.

Key Features

• YAML-defined templates: HTTP, DNS, TCP, headless browser, code execution
• 9,000+ community templates (nuclei-templates repository)
• Parallel scanning with rate limiting and retries
• AI endpoint checks: exposed OpenAI API proxies, unsecured Ollama, HuggingFace misconfiguration
• CI/CD integrations (GitHub Actions, Jenkins, GitLab CI)

Quick Start

# Install
go install -v github.com/projectdiscovery/nuclei/v3/cmd/nuclei@latest
