GitHub CodeQL is licensed on a per-user basis upon installation. You can use CodeQL only for certain tasks under the license restrictions. If you have a GitHub Advanced Security license, you can use CodeQL for automated analysis, continuous integration, and codeql delivery, codeql. To analyze a codebase, you run queries against a CodeQL database extracted codeql the code.

GitHub CodeQL is licensed on a per-user basis upon installation. You can use CodeQL only for certain tasks under the license restrictions. If you have a GitHub Advanced Security license, you can use CodeQL for automated analysis, continuous integration, and continuous delivery. Software developers and security researchers can secure their code using CodeQL analysis. Its main purpose is to generate a database representation of a codebase, a CodeQL database. Once the database is ready, you can query it interactively, or run a suite of queries to generate a set of results in SARIF format and upload the results to GitHub.

CodeQL is a static analysis tool that can be used to automatically scan your applications for vulnerabilities and to assist with a manual code review. Below, we include voluntary challenges, but it is highly recommended to do them while reading through the blog to get a better understanding of CodeQL, how to use it, and learn a few new tips and tricks about the tool. The first part of the CodeQL zero to hero series introduced some of the fundamental concepts of static analysis for vulnerability research—sources, sinks, data flow analysis, and taint analysis taint tracking. Data flow analysis is a static analysis method that is commonly used to track untrusted inputs in the code sources and find if they are used in dangerous functions sinks. CodeQL offers automated scanning for vulnerabilities and can also be used as a tool to explore codebases and to assist with manual testing. CodeQL is a powerful static code analysis tool developed by Semmle acquired by GitHub in and based on over decade of research by a team from Oxford University. CodeQL uses data flow analysis and taint analysis to find code errors, check code quality, and identify vulnerabilities. The key idea behind CodeQL is that it analyzes code as data by creating a database of facts about your program and then using a special query language, called QL, to query the database for vulnerable patterns. Once we have the CodeQL database, we can ask it some questions queries about patterns that we want to find in the source code. QL is an expressive, declarative, logical query language for identifying patterns in the database, that is vulnerabilities, for example, SQL injection.

The technique can be used to perform various checks, verification, and to highlight issues in the code. At Github, we perform static analysis in code scanning via CodeQL, our semantic analysis engine. This blog series will give you an introduction to static analysis concepts, an overview of CodeQL, how you can leverage static analysis for security research, and teach you how to write custom CodeQL queries. It is possible to start using CodeQL and find vulnerabilities without digging into static analysis by using the predefined queries in the default configuration check out our CodeQL documentation. However, learning static analysis fundamentals will enable you to define and query for specific patterns or vulnerabilities. As you dig into vulnerability research with CodeQL, we hope you will find many of these concepts useful for writing your own queries and getting precise alert results. To facilitate learning static analysis, vulnerability research, and CodeQL, this blog contains voluntary challenges. There are many types of vulnerabilities—some are easier to find with static analysis, some with other means, and some can only be found through manual analysis. One of the types of vulnerabilities that static analysis can find are injection vulnerabilities, which encompass tens of subtypes, and those are the ones that we are going to focus on.

Yet in recent years, quantum computing has become a hot topic, especially in the world of cryptography. Post-quantum cryptography raises many questions and challenges, and a group of researchers and security experts across GitHub, Santander, and Microsoft came together to start trying to tackle them. They started with a question: how do you understand how cryptography is used and implemented, whether it be on-prem or in the cloud, across hundreds of thousands if not millions of lines of code? To tackle this initial problem, the team decided to use a number of building blocks to create queries and run them at scale. CodeQL allows you to model applications like data and then run queries against that data. Once the team had the queries they wanted to run, they needed a way to scale them across thousands of repositories. This is where multi-repository variant analysis MRVA came into play.
