CybeDefend’s Dataflow Analysis gives you deeper insights into how a vulnerability travels through your code. We focus on whether a vulnerable line references a static value or a variable:

​
How It Works

CybeDefend AI identifies a vulnerable line post-scan. It checks if the flag relates to:

  • A static element (e.g., password, string literal).
  • A variable (e.g., userInput, configParam).

If static, AI marks it for immediate review (e.g., “Hardcoded Credential”). If a variable is involved, our Variable Dataflow Tracer inspects the codebase to see how the variable flows—tracing it back to its origin and following every use along the path.

This combined process enables you to quickly pinpoint the critical steps in your code that truly matter, reducing noise and improving fix times.

This feature is in early alpha and will continue to evolve. If you have feedback, please share it with us so we can refine multi-file capabilities and expand language coverage.

About the Variable Dataflow Tracer

The Variable Dataflow Tracer is an open-source tool developed by CybeDefend to perform variable-specific dataflow analysis across multiple languages (e.g., Go, Python, Java, JavaScript, C/C++, C#, PHP, Ruby, Rust). It can be run standalone as a CLI or integrated as a library, and it:

  • Locates a variable at a given line in code.
  • Builds a graph of where that variable originates and how it’s used.
  • Highlights potential vulnerabilities or logic flaws along the path.

Here’s a quick overview of its key features:

  • Multilingual Support: Traces variables in several languages and frameworks.
  • Recursive Data Flow: Tracks a variable from source to sink, mapping function calls along the way.
  • Open Source: Licensed under Apache 2, contributions are welcome.
