Nuclei — Template-Based Vulnerability Scanner
ProjectDiscovery's fast, template-driven vulnerability scanner with 9,000+ community templates for web apps, APIs, cloud, and AI service endpoints.
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
# Scan a target with all CVE templates
nuclei -u https://api.example.com -t cves/
# Custom AI endpoint template
nuclei -u http://localhost:11434 -t ai/

Compromise signals — malicious or tampered code (leaked secrets, backdoors, a dropped executable) — reduce the score, and known dependency CVEs carry a bounded penalty (they warrant review but never QUARANTINE — update the dependency to clear). Other dangerous-by-capability traits are risk surface, expected for some capabilities. Every finding is mapped to its OWASP control below.
Findings mapped to the OWASP Top 10 for LLM Applications (2025) and the OWASP Machine Learning Security Top 10. Expand any flagged control for the exact findings — compromise reduces the score; expected/risk-surface do not, except a known CVE, which carries a small bounded penalty (high/critical → Review).
