SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps security engineers locate vulnerability variants and related bugs across large codebases using pattern-based analysis and standardized search strategies.

Core Features & Use Cases

  • Variant hunting: Identify similar vulnerability patterns across modules and repositories.
  • Query refinement: Build and refine CodeQL/Semgrep queries to cover related variants.
  • Systematic audits: Perform cross-project code audits after an initial issue is discovered.

Quick Start

Provide the initial vulnerability pattern and run a cross-repo search to discover variant paths across the codebase.

FAQPage Schema
How do I find vulnerability variants across a codebase after finding an initial bug?▼

To find vulnerability variants across a codebase, provide an initial vulnerability pattern to run cross-repo searches and discover similar bug paths across modules and repositories using standardized search strategies.

Can I use Semgrep and CodeQL queries for cross-project code audits?▼

Yes, you can build and refine CodeQL and Semgrep queries for cross-project code audits. The skill applies pattern-based analysis to systematically locate related vulnerability variants across multiple projects.

What is pattern-based variant analysis for security engineering?▼

Pattern-based variant analysis is a security engineering technique that identifies similar vulnerability patterns across modules. It supports exact and generalized pattern matching within a root-cause framework to systematically hunt bug variants.

Does variant analysis support cross-language searches within a single repository?▼

Yes, variant analysis supports cross-language searches within a root-cause framework. It applies generalized pattern matching to locate vulnerability variants across different programming languages in the same codebase.

What is the best way to systematically hunt bug variants after discovering an issue?▼

The best way to systematically hunt bug variants is providing the initial vulnerability pattern to run a cross-repo search. This applies standardized search strategies to discover variant paths across the entire codebase.

How do I refine CodeQL queries to cover related vulnerability variants?▼

You refine CodeQL queries by applying pattern-based analysis to the initial vulnerability. This helps locate related vulnerability variants across the codebase and systematically builds queries to cover all similar bug patterns.
