CodeQL

Definitions

1. A code analysis engine and query language developed for finding security issues and other patterns by modeling source code semantically rather than just searching text. CodeQL lets teams write queries against code databases to detect data-flow problems, unsafe APIs, and project-specific patterns across large repositories.

   In plain English: A tool and query language for deeply analyzing source code to find security and quality issues.

   Example: "The security team used CodeQL to catch a tainted data path from request input into a dangerous file operation that ordinary grep-based checks had missed."
