This version of GitHub Enterprise Server was discontinued on 2024-01-04. No patch releases will be made, even for critical security issues. For better performance, improved security, and new features, upgrade to the latest version of GitHub Enterprise Server. For help with the upgrade, contact GitHub Enterprise support.

Customizing analysis with CodeQL packs

You can use CodeQL packs to run CodeQL queries maintained by other people, or to share CodeQL queries that you've developed.


GitHub CodeQL is licensed on a per-user basis upon installation. You can use CodeQL only for certain tasks under the license restrictions. For more information, see "About the CodeQL CLI."

If you have a GitHub Advanced Security license, you can use CodeQL for automated analysis, continuous integration, and continuous delivery. For more information, see "About GitHub Advanced Security."

Note: The CodeQL package management functionality, including CodeQL packs, is currently available as a beta release and is subject to change. During the beta release, CodeQL packs are available only using GitHub Packages - the Container registry. To use this beta functionality, install the latest version of the CodeQL CLI bundle from:

About CodeQL packs

Note: This article describes the features available with the CodeQL CLI 2.12.7 bundle included in the initial release of GitHub Enterprise Server 3.7.

If your site administrator has updated your CodeQL CLI version to a newer release, please see the GitHub Enterprise Cloud version of this article for information on the latest features.

CodeQL packs are used to create, share, depend on, and run CodeQL queries and libraries. CodeQL packs contain queries, library files, query suites, and metadata. You can customize your CodeQL analysis by downloading packs created by others and running them on your codebase.

There are two types of CodeQL packs: query packs and library packs.

  • Query packs contain a set of pre-compiled queries that can be evaluated on a CodeQL database. Query packs are designed to be run. When a query pack is published, the bundle includes all the transitive dependencies and a compilation cache. This ensures consistent and efficient execution of the queries in the pack.

  • Library packs are designed to be used by query packs (or other library packs) and do not contain queries themselves. The libraries are not compiled and there is no compilation cache included when the pack is published.

The standard CodeQL packs for all supported languages are published in the Container registry. If you installed the CodeQL CLI in the standard way, using the CodeQL CLI bundle, the core query packs are already downloaded and available to you. They are:

  • codeql/cpp-queries
  • codeql/csharp-queries
  • codeql/go-queries
  • codeql/java-queries
  • codeql/javascript-queries
  • codeql/python-queries
  • codeql/ruby-queries

You can also use the CodeQL CLI to create your own CodeQL packs, add dependencies to packs, and install or update dependencies. For more information, see "Creating and working with CodeQL packs."

You can publish CodeQL packs that you have created, using the CodeQL CLI. For more information on publishing and downloading CodeQL packs, see "Publishing and using CodeQL packs."

Downloading and using CodeQL query packs

The CodeQL CLI bundle includes queries that are maintained by GitHub experts, security researchers, and community contributors. If you want to run queries developed by other organizations, CodeQL query packs provide an efficient and reliable way to download and run queries. For more information about query packs, see "About code scanning with CodeQL."

Before you can use a CodeQL query pack to analyze a database, you must download any packages you require from the GitHub Container registry. This can be done either by using the --download flag as part of the codeql database analyze command, or running codeql pack download. If a package is not publicly available, you will need to use a GitHub App or personal access token to authenticate. For more information and an example, see "Uploading CodeQL analysis results to GitHub."

<scope/name@version:path>Specify the scope and name of one or more CodeQL query packs to download using a comma-separated list. Optionally, include the version to download and unzip. By default the latest version of this pack is downloaded. Optionally, include a path to a query, directory, or query suite to run. If no path is included, then run the default queries of this pack.
--github-auth-stdinPass the CLI the GitHub App or personal access token created for authentication with GitHub's REST API from your secret store via standard input. This is not needed if the command has access to a GITHUB_TOKEN environment variable set with this token.

Basic example of downloading and using query packs

This example runs the codeql database analyze command with the --download option to:

  1. Download the latest version of the octo-org/security-queries pack.
  2. Download a version of the octo-org/optional-security-queries pack that is compatible with version 1.0.1 (in this case, it is version 1.0.2). For more information on semver compatibility, see npm's semantic version range documentation.
  3. Run all the default queries in octo-org/security-queries.
  4. Run only the query queries/csrf.ql from octo-org/optional-security-queries
$ echo $OCTO-ORG_ACCESS_TOKEN | codeql database analyze --download /codeql-dbs/example-repo \
    octo-org/security-queries \
    octo-org/optional-security-queries@~1.0.1:queries/csrf.ql \
    --format=sarif-latest --output=/temp/example-repo-js.sarif

Direct download of CodeQL packs

If you want to download a CodeQL pack without running it immediately, then you can use the codeql pack download command. This is useful if you want to avoid accessing the internet when running CodeQL queries. When you run the CodeQL analysis, you can specify packs, versions, and paths in the same way as in the previous example:

echo $OCTO-ORG_ACCESS_TOKEN | codeql pack download <scope/name@version:path> <scope/name@version:path> ...

Downloading CodeQL packs from multiple GitHub container registries

If your CodeQL packs reside on multiple container registries, then you must instruct the CodeQL CLI where to find each pack. For more information, see "Customizing code scanning."

Specifying which queries to run in a CodeQL pack

Query specifiers are used by codeql database analyze and other commands that operate on a set of queries. The complete form of a query specifier is scope/name@range:path, where:

  • scope/name is the qualified name of a CodeQL pack.
  • range is a semver range.
  • path is a file system path to a single query, a directory containing queries, or a query suite file.

When you specify a scope/name, the range and path are optional. If you omit a range then the latest version of the specified pack is used. If you omit a path then the default query suite of the specified pack is used.

The path can be one of: a .ql query file, a directory containing one or more queries, or a .qls query suite file. If you omit a pack name, then you must provide a path, which will be interpreted relative to the working directory of the current process. Glob patterns are not supported.

If you specify both a scope/name and path, then the path cannot be absolute. It is considered relative to the root of the CodeQL pack.

Example query specifiers

  • codeql/python-queries - All the queries in the default query suite of the latest version of the codeql/python-queries pack.

  • codeql/python-queries@1.2.3 - All the queries in the default query suite of version 1.2.3 of the codeql/python-queries pack.

  • codeql/python-queries@~1.2.3 - All the queries in the default query suite of the latest version of the codeql/python-queries pack that is >= 1.2.3 and < 1.3.0.

  • codeql/python-queries:Functions - All queries in the Functions directory in the latest version of the codeql/python-queries pack.

  • codeql/python-queries@1.2.3:Functions - All queries in the Functions directory in version 1.2.3 of the codeql/python-queries pack.

  • codeql/python-queries@1.2.3:codeql-suites/python-code-scanning.qls - All queries in the codeql-suites/python-code-scanning.qls directory in version 1.2.3 of the codeql/python-queries pack.

  • suites/my-suite.qls - All queries in the suites/my-suite.qls file relative to the current working directory.


The default query suite of the standard CodeQL query packs are codeql-suites/<lang>-code-scanning.qls. Several other useful query suites can also be found in the codeql-suites directory of each pack. For example, the codeql/cpp-queries pack contains the following query suites:

  • cpp-code-scanning.qls - Standard Code Scanning queries for C++. The default query suite for this pack.

  • cpp-security-extended.qls - Queries from the default cpp-code-scanning.qls suite for C++, plus lower severity and precision queries.

  • cpp-security-and-quality.qls - Queries from cpp-security-extended.qls, plus maintainability and reliability queries.

You can see the sources for these query suites in the CodeQL repository. Query suites for other languages are similar.
