FAQPage Schema

How do I find similar code vulnerabilities across multiple repositories?▼

To find similar code vulnerabilities across multiple repositories, you can apply pattern-based variant analysis. This process identifies and maps all code patterns matching a known vulnerability to accelerate security audits and remediation.

What is variant analysis in static code analysis?▼

Variant analysis in static code analysis is the technique of identifying and mapping all code patterns that match a known vulnerability across a codebase. It supports QA and security audits by discovering variant manifestations of bugs.

How do I build CodeQL or Semgrep queries to hunt for security patterns?▼

You can build or refine CodeQL and Semgrep queries for security patterns by analyzing a known vulnerability pattern in your repository. This guides precise pattern definitions for tool-assisted searches across multiple codebases.

Can I use variant analysis for cross-repo bug hunting and triage?▼

Yes, you can use variant analysis for cross-repo bug hunting and triage. It applies pattern-based searches across multiple repositories to discover bug variants, providing structured analysis and triage guidance for root causes.

Do I need a precise pattern definition to start finding bug variants?▼

Yes, finding bug variants requires precise pattern definitions. You must analyze the known vulnerability pattern in your repo first, as precise definitions are necessary to guide tool-assisted searches and accurate variant discovery.
