SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill resolves the ambiguity between genuine security vulnerabilities and outdated or placeholder tests, ensuring engineering teams focus their efforts on fixing actual exploit paths rather than chasing false positives.

Core Features & Use Cases

  • Exploit Path Analysis: Provides a systematic approach to trace attacker input from entry points to sensitive sinks.
  • Test Validation: Offers criteria to determine if a test exercises production code or relies on synthetic, non-authoritative helpers.
  • Use Case: When a security test fails, use this Skill to determine if the failure represents a critical regression in redirect handling or if the test itself is stale and requires refactoring to match current production security patterns.

Quick Start

Analyze the failing security test by tracing the input path from the controller to the redirect sink as defined in the security regression triage workflow.

Frequently Asked Questions about Security Regression Triage

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

FAQPage Schema
How do I tell if a failing security test is a real exploit or a stale assertion?▼

To distinguish a real exploit from a stale test assertion, trace the attacker input path from the controller entry point to the redirect sink. This verifies whether the test exercises production code or relies on synthetic, non-authoritative helpers.

What is the best way to triage security regression failures in ASP.NET Core authentication?▼

Triage security regression failures in ASP.NET Core authentication by analyzing the exploit path and validating defense-in-depth boundaries. This determines if the failure represents a critical redirect handling regression or an outdated test requiring refactoring.

How do I validate redirect handling and input sanitization during security triage?▼

Validate redirect handling and input sanitization during security triage by verifying that security boundaries are enforced at both the controller and callback execution contexts. This confirms genuine exploit coverage against placeholder assertions.

Does this security triage approach work with CWE-601 redirect validation workflows?▼

Yes, this security triage approach works with CWE-601 redirect validation workflows by systematically tracing attacker input to sensitive sinks. It ensures engineering teams focus on fixing actual open redirect exploit paths rather than chasing false positives.

Why does my security test fail when the production authentication code seems correct?▼

Your security test fails because the test itself may be stale and requires refactoring to match current production security patterns. Security regression triage distinguishes between genuine exploit coverage and outdated placeholder assertions to resolve this ambiguity.

When should I refactor a failing security test instead of fixing the production code?▼

You should refactor a failing security test instead of fixing production code when the test relies on synthetic, non-authoritative helpers. Security regression triage identifies if the failure represents a stale assertion rather than a critical regression in redirect handling.
