GitHub Action running Nuclei on single URL

      - name: Nuclei - Vulnerability Scan
        uses: projectdiscovery/nuclei-action@main
        with:
          target: https://example.com

GitHub Action running Nuclei with custom templates

      - name: Nuclei - Vulnerability Scan
        uses: projectdiscovery/nuclei-action@main
        with:
          target: https://example.com
          templates: custom_template_path

As default, all the default nuclei-templates are used for scan.

GitHub Action running Nuclei with custom workflows

      - name: Nuclei - Vulnerability Scan
        uses: projectdiscovery/nuclei-action@main
        with:
          target: https://example.com
          workflows: custom_workflow_path

GitHub Action running Nuclei on multiple URLs

      - name: Nuclei - Vulnerability Scan
        uses: projectdiscovery/nuclei-action@main
        with:
          urls: urls.txt

GitHub Action running Nuclei with CLI flags

      - name: Nuclei - Vulnerability Scan
        uses: projectdiscovery/nuclei-action@main
        with:
          urls: urls.txt
          flags: "-severity critical,high,medium,low -stats"

GitHub Action running Nuclei with Custom UA

      - name: Nuclei - Vulnerability Scan
        uses: projectdiscovery/nuclei-action@main
        with:
          urls: urls.txt
          user-agent: "User-Agent:'Nuclei - Vulnerability Scan (Have a nice day)'"

GitHub Action running Nuclei with Config files

      - name: Nuclei - Vulnerability Scan
        uses: projectdiscovery/nuclei-action@main
        with:
          urls: urls.txt
          config: config.yaml
          report-config: issues.yaml

GitHub Example Action running Nuclei with GitHub Issue reporting

Setting permissions for GITHUB_TOKEN, according to the github actions docs.

permissions:
  issues: write

      - name: Nuclei - Vulnerability Scan
        uses: projectdiscovery/nuclei-action@main
        with:
          target: https://example.com
          github-report: true
          github-token: ${{ secrets.GITHUB_TOKEN }}

Using the github-report creates a default configuration to enable reporting to Github Issues

GitHub Example Action running Nuclei with custom GitHub Issue reporting

      - name: Nuclei - Vulnerability Scan
        uses: projectdiscovery/nuclei-action@main
        with:
          target: https://example.com
          report-config: github-issue-config.yaml
          github-token: ${{ secrets.GITHUB_TOKEN }}

Create a yaml file to define the nuclei github issue reporting behavior:

github:
  duplicate-issue-check: true
  severity-as-label: true
  issue-label: '<Nuclei Scan Vulnerability>'

The nuclie-action will fill in the repository settings into the custom configuration. The file don't need to be augmented with these information manually.

github:
  username: GITHUB_ACTOR,
  owner: GITHUB_REPOSITORY_OWNER,
  token,
  "project-name": GITHUB_REPOSITORY,

Contributing

This action uses Javascript github actions toolkit. Code using the src directory, and before submitting your PR, check and run a npm run build, otherwise your changes will not be applied to the final action which resides in the dist directory.

We use this way to avoid jobs having to install npm modules and create a final version without dependencies on our code.
