How can you customize CodeQL queries to target a specific library or framework in your project?

• A. Install CodeQL and run a separate external analyzer.
• B. Configure CodeQL to run without any queries.
• C. Use default CodeQL queries only and do not customize them.
• D. Create custom CodeQL queries or packs specific to the library/framework and configure the workflow to use them during analysis.

Answer: (D)

Customizing CodeQL to target a specific library or framework means writing your own CodeQL queries (or creating a CodeQL pack) that understand that library’s API and its common usage patterns, and then configuring your analysis to run those queries. By building queries that model how the library is intended to be used—what calls flow data where, what constitutes unsafe usage, and what API misuse looks like—you get targeted scans that can detect issues the generic queries might miss. A library-specific pack can bundle these queries, declare the relevant API surfaces, and be referenced in your CI workflow so the analysis runs exactly these targeted checks. This focused approach provides precise coverage for the framework’s typical scenarios, rather than relying on broad, default queries that may overlook library-specific vulnerabilities. Running CodeQL with no queries or relying on only default queries won’t address the library’s unique risks, and using an external analyzer would not leverage CodeQL’s query-based, customizable strength.
