  • Update nuclei templates to the latest released version (downloaded to ~/nuclei-templates on macOS/Linux or %USERPROFILE%\nuclei-templates on Windows):

nuclei {{[-ut|-update-templates]}}

  • [l]ist all [t]emplates by specific [p]rotocol [t]ype:

nuclei -tl {{[-pt|-type]}} {{dns|file|http|headless|tcp|workflow|ssl|websocket|whois|code|javascript}}

  • Run an automatic web scan using Wappalyzer technology detection for a specific target [u]RL/host:

nuclei {{[-as|-automatic-scan]}} {{[-u|-target]}} {{example.com}}

  • Run HTTP [p]rotocol [t]ype templates of specific severity, exporting results to markdown files inside a specific directory:

nuclei {{[-s|-severity]}} {{high,critical,...}} {{[-pt|-type]}} http {{[-u|-target]}} {{https://example.com}} {{[-me|-markdown-export]}} {{path/to/directory}}

  • Run all templates with a custom rate limit, maximum bulk size, and silent output (only findings shown):

nuclei {{[-rl|-rate-limit]}} {{150}} {{[-bs|-bulk-size]}} {{25}} {{[-c|-concurrency]}} {{25}} -silent {{[-u|-target]}} {{https://example.com}}

  • Run a specific nuclei-bundled workflow against a target:

nuclei {{[-w|-workflows]}} {{workflows/wordpress-workflow.yaml}} {{[-u|-target]}} {{https://example.com}}

  • Run one or more specific templates or directory with templates with verbose output in stderr and output detected issues/vulnerabilities to a file:

nuclei {{[-t|-templates]}} {{path/to/nuclei-templates/http}} {{[-u|-target]}} {{https://example.com}} {{[-v|-verbose]}} {{[-o|-output]}} {{path/to/results}}

  • Run a scan based on one or more template conditions:

nuclei {{[-tc|-template-condition]}} "{{contains(tags, 'xss') && contains(tags, 'cve')}}" {{[-u|-target]}} {{https://example.com}}
