Scanning Input Validation Practices

This skill automates the process of identifying potential input validation flaws within a codebase. By analyzing how user-provided data is handled, it helps developers proactively address security vulnerabilities before they can be exploited. This skill streamlines security audits and improves the overall security posture of applications.

What this skill does

This skill enables Claude to automatically scan source code for potential input validation vulnerabilities. It identifies areas where user-supplied data is not properly sanitized or validated before being used in operations, which could lead to security exploits like SQL injection, cross-site scripting (XSS), or command injection. Use this skill when the user asks to "scan for input validation issues", "check input sanitization", "find potential XSS vulnerabilities", or similar requests related to securing user input. It is particularly useful during code reviews, security audits, and when har

Trigger phrases

Claude loads this skill automatically when you say things like:

“scan for input validation issues”“check input sanitization”“find potential XSS vulnerabilities”

How it works

  1. Code Analysis: The skill uses the input-validation-scanner plugin to analyze the specified codebase or file.
  2. Vulnerability Identification: The plugin identifies instances where input validation may be missing or insufficient.
  3. Report Generation: The skill presents a report highlighting potential vulnerabilities and their locations in the code.

When to use it

  • Audit a codebase for input validation vulnerabilities.
  • Review newly written code for potential XSS or SQL injection flaws.
  • Harden an application against common web security exploits.
  • Ensure compliance with security best practices related to input handling.

Best practices

  • Contextual Analysis: Always review the identified vulnerabilities in context to determine their actual impact and severity.
  • Comprehensive Validation: Ensure that all user-supplied data is validated, including data from forms, APIs, and external sources.
