SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps security teams identify and confirm storage-type XSS risk chains by linking user input through persistence to its eventual render sink, turning scattered findings into a verifiable risk narrative.

Core Features & Use Cases

  • Leverages existing audit workflows (sast-scan, dataflow-analysis, file-upload) to assemble end-to-end XSS chains.
  • Provides a structured methodology for entry points, persistence points, and render-time sinks, with concrete guidance and references.
  • Supports reproducible evidence collection and reporting by aligning with the included references to illustrate common attack patterns.

Quick Start

Analyze an example project to enumerate input -> persistence -> render sinks and generate a findings-ready report.

FAQPage Schema
How do I trace stored XSS vulnerabilities from user input to render sinks?▼

Stored XSS detection identifies risk chains by linking user input through database persistence to render sinks, turning scattered application findings into a verifiable security risk narrative.

How do I audit web applications for storage-type XSS risk chains?▼

You audit web apps for storage XSS by enumerating entry points, persistence points, and render-time sinks, then applying dataflow analysis to assemble reproducible evidence of attack patterns.

Does stored XSS detection integrate with existing SAST scan and dataflow analysis workflows?▼

Yes, this approach leverages existing SAST scan and dataflow analysis workflows to assemble end-to-end XSS chains and evaluate sanitization coverage within code auditing pipelines.

What is the best way to confirm storage XSS risks during a security review?▼

The best way to confirm storage XSS risks is aligning entry, persistence, and sink points with concrete references to illustrate common attack patterns for reproducible evidence collection.

Can I use stored XSS detection for rich text rendering components in web apps?▼

Yes, stored XSS detection is specifically applied to web apps that store user input and render it in HTML or rich text, evaluating sanitization and coverage criteria.
