CodeQL Action
This action runs GitHub's industry-leading semantic code analysis engine, CodeQL, against a repository's source code to find security vulnerabilities. It then automatically uploads the results to GitHub so they can be displayed in the repository's security tab. CodeQL runs an extensible set of queries, which have been developed by the community and the GitHub Security Lab to find common vulnerabilities in your code.
For a list of recent changes, see the CodeQL Action's changelog.

Usage
This is a short walkthrough, but for more information read configuring code scanning.
To get code scanning results from CodeQL analysis on your repo you can use the following workflow as a template:
name: "Code Scanning - Action"
on:
push:
branches: [main]
pull_request:
branches: [main]
schedule:
# โโโโโโโโโโโโโโ minute (0 - 59)
# โ โโโโโโโโโโโโโโ hour (0 - 23)
# โ โ โโโโโโโโโโโโโโ day of the month (1 - 31)
# โ โ โ โโโโโโโโโโโโโโ month (1 - 12 or JAN-DEC)
# โ โ โ โ โโโโโโโโโโโโโโ day of the week (0 - 6 or SUN-SAT)

# Autobuild attempts to build any compiled languages (C/C++, C#, Go, or Java).

#- run: |

- name: Perform CodeQL Analysis
uses: github/codeql-action/analyze@v2If you prefer to integrate this within an existing CI workflow, it should end up looking something like this:
- name: Initialize CodeQL
uses: github/codeql-action/init@v2
with:
languages: go, javascript
# Here is where you build your code
- run: |
make bootstrap
make release
- name: Perform CodeQL Analysis
uses: github/codeql-action/analyze@v2Configuration file
Use the config-file parameter of the init action to enable the configuration file. The value of config-file is the path to the configuration file you want to use. This example loads the configuration file ./.github/codeql/codeql-config.yml.
- uses: github/codeql-action/init@v2
with:
config-file: ./.github/codeql/codeql-config.ymlThe configuration file can be located in a different repository. This is useful if you want to share the same configuration across multiple repositories. If the configuration file is in a private repository you can also specify an external-repository-token option. This should be a personal access token that has read access to any repositories containing referenced config files and queries.
- uses: github/codeql-action/init@v2
with:
config-file: owner/repo/codeql-config.yml@branch
external-repository-token: ${{ secrets.EXTERNAL_REPOSITORY_TOKEN }}For information on how to write a configuration file, see "Using a custom configuration file."
If you only want to customise the queries used, you can specify them in your workflow instead of creating a config file, using the queries property of the init action:
- uses: github/codeql-action/init@v2
with:
queries: <local-or-remote-query>,<another-query>By default, this will override any queries specified in a config file. If you wish to use both sets of queries, prefix the list of queries in the workflow with +:
- uses: github/codeql-action/init@v2
with:
queries: +<local-or-remote-query>,<another-query>Configuration via config input
You can alternatively configure CodeQL using the config input to the init Action. The value of this input must be a YAML string that follows the configuration file format documented at "Using a custom configuration file."
Example configuration
- uses: github/codeql-action/init@v2
with:
languages: ${{ matrix.language }}
config: |
disable-default-queries: true
queries:
- uses: security-extended
- uses: security-and-quality
query-filters:
- include:
tags: /cwe-020/Sharing configuration across multiple repositories
You can use Actions or environment variables to share configuration across multiple repositories and to modify configuration without needing to edit the workflow file. In the following example, vars.CODEQL_CONF is an Actions configuration variable:
- uses: github/codeql-action/init@v2
with:
languages: ${{ matrix.language }}
config: ${{ vars.CODEQL_CONF }}Troubleshooting
