SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) and assets (resource) components.

What problem does it solve?

This Skill helps you systematically find similar vulnerabilities and bugs across a codebase once an initial pattern has been identified, significantly improving security auditing efficiency.

Core Features & Use Cases

Variant Hunting: Search for code patterns that mirror a known vulnerability.
Query Development: Assist in building and refining Semgrep or CodeQL queries.
Systematic Audits: Perform in-depth code reviews focused on specific vulnerability classes.
Use Case: After discovering a SQL injection vulnerability in one part of an application, use this Skill to search the entire codebase for other instances of user input being directly incorporated into SQL queries.

Quick Start

Use the variant-analysis skill to find patterns similar to the provided code snippet in the current project.

FAQPage Schema

How do I find similar vulnerabilities across a codebase after finding one bug?▼

Variant analysis involves systematically searching a codebase for code patterns that mirror a known vulnerability, significantly improving security auditing efficiency by discovering similar bugs based on identified patterns.

Can I use this to build Semgrep or CodeQL queries for code audits?▼

Yes, this approach supports security auditing by assisting in building and refining Semgrep or CodeQL queries, enabling in-depth code reviews focused on specific vulnerability classes.

What is variant analysis in the context of code security?▼

Variant analysis is a security auditing technique used to discover similar vulnerabilities and bugs across a codebase once an initial pattern has been identified through root cause analysis and iterative pattern generalization.

What do I need to know before hunting for bug variants in my project?▼

Hunting for bug variants requires an understanding of root cause analysis and iterative pattern generalization to effectively identify similar vulnerabilities across a codebase based on a provided code snippet.

How do I search an entire application for other instances of a SQL injection pattern?▼

You can use variant analysis to search the entire codebase for other instances of user input being directly incorporated into SQL queries, expanding the audit from a single identified vulnerability.
