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. ## How It Works 1. **Initiate Scan**: The user requests an input validation scan, triggering the skill. 2. **Code Analysis**: The skill uses the input-validation-scanner plugin to analyze the specified codebase or file. 3. **Vulnerability Identification**: The plugin identifies instances where input validation may be missing or insufficient. 4. **Report Generation**: The skill presents a report highlighting potential vulnerabilities and their locations in the code. ## When to Use This Skill This skill activates when you need to: - 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. ## Examples ### Example 1: Identifying XSS Vulnerabilities User request: "Scan the user profile module for potential XSS vulnerabilities." The skill will: 1. Activate the input-validation-scanner plugin on the specified module. 2. Generate a report highlighting areas where user input is directly rendered without proper sanitization, indicating potential XSS vulnerabilities. ### Example 2: Checking for SQL Injection Risks User request: "Check the database access layer for potential SQL injection risks." The skill will: 1. Use the input-validation-scanner plugin to examine the database access code. 2. Identify instances where user input is used directly in SQL queries without proper parameterization or escaping, indicating potential SQL injection vulnerabilities. ## Best Practices - **Regular Scanning**: Integrate input validation scanning into your regular development workflow. - **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. ## Integration This skill can be used in conjunction with other security-related skills to provide a more comprehensive security assessment. For example, it can be combined with a static analysis skill to identify other types of vulnerabilities or with a dependency scanning skill to identify vulnerable third-party libraries. --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/jeremylongshore) — claim your Tome and manage your conversions.
