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. To analyze a codebase, you run queries against a CodeQL database extracted from the code. CodeQL analyses produce results that can be uploaded to GitHub to generate code scanning alerts. When you upload the results to GitHub, code scanning uses this category to store the results for each language separately. If you forget to do this, each upload overwrites the previous results. You can specify additional options depending on what analysis you want to do. If this step is necessary, then you will see a message telling you that your database needs to be upgraded when you run database analyze. Explicitly running the upgrade command is not necessary. For full details of all the options you can use when analyzing databases, see " database analyze. This is essential when you have more than one CodeQL database to analyze for a single commit in a repository.

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.

Discover vulnerabilities across a codebase with CodeQL, our industry-leading semantic code analysis engine. CodeQL lets you query code as though it were data. Write a query to find all variants of a vulnerability, eradicating it forever. Then share your query to help others do the same. See how powerful it is to discover a bad pattern and then find similar occurrences across the entire codebase.

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.

Configure secret scans. Preparing code for analysis. The query for it will look as follows. Using the data flow graph we can query if there is a connection between, for example, a source of user-controlled data and a SQL injection sink.

Yet in recent years, quantum computing has become a hot topic, especially in the world of cryptography.
