To perform static analysis for vulnerability detection, you execute custom queries against a code property graph. This allows you to traverse complex code relationships and identify patterns like unsanitized function calls across large codebases.

A code property graph (CPG) combines abstract syntax trees, control flow, and program dependencies into a unified graph database. You need a CPG for security auditing when searching for complex structural anomalies that standard grep or regex tools cannot find.

Yes, you need a running Joern server and a pre-initialized CPG binary to function correctly. The skill provides a direct interface to the Joern query engine, sending your custom graph queries to the server for execution.

The best way to analyze call graphs for sensitive functions is leveraging a graph database to traverse code relationships. By querying the code property graph, you can pinpoint exact instances where specific functions receive un sanitized inputs.

You can use regex or grep for simple pattern matching, but they cannot traverse complex code relationships. A code property graph is required to understand structural anomalies and data flow across large codebases during security auditing.
