SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Identify and generalize vulnerability patterns across a codebase to surface variants that match known issues, enabling proactive detection and faster remediation.

Core Features & Use Cases

  • Variant discovery across languages and patterns to locate related issues after a security advisory.
  • Generalization of bug patterns to build broader detection rules.
  • Guided triage and rule creation using Semgrep, CodeQL, and grep/ripgrep, with integration into CI pipelines.

Quick Start

Describe a known vulnerability exemplar and run targeted searches with Semgrep, CodeQL, or grep to surface related variants.

Frequently Asked Questions about variant-analysis

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I find vulnerability variants across a codebase after a security advisory?▼

Vulnerability variant analysis generalizes a known bug pattern and runs targeted searches across a codebase to surface related issues, enabling proactive detection and faster remediation.

What is the best way to generalize a bug pattern for multi-language detection?▼

Generalizing a bug pattern involves describing a known vulnerability exemplar and using pattern-matching tools to detect similar variants across multiple languages and platforms.

Can I use Semgrep, CodeQL, and grep together for variant detection?▼

Yes, variant analysis supports multi-language matching and guided triage using Semgrep, CodeQL, and grep/ripgrep to locate related vulnerabilities and create persistent detection rules.

How do I create persistent detection rules for ongoing vulnerability detection?▼

After discovering vulnerability variants, you can generalize the bug pattern into persistent detection rules and integrate them into CI pipelines for continuous security monitoring.

Does variant analysis work across different programming languages and platforms?▼

Yes, variant analysis performs multi-language matching to locate related vulnerability variants across diverse platforms and languages after a security advisory or during audits.

When should I use variant analysis for secure code maintenance?▼

Variant analysis is applicable during security audits, after publishing security advisories, and for ongoing detection to surface related vulnerability variants across codebases.
