SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Perl applications are highly vulnerable to critical security flaws including injection attacks, path traversal, XSS, and code execution if secure coding practices are not consistently applied, leading to data breaches, system compromise, and compliance failures.

Core Features & Use Cases

  • Taint Mode & Input Validation: Enforce strict input sanitization and allowlist-based validation to block malicious payloads from external sources.
  • Injection Prevention: Implement parameterized DBI queries and safe list-form process execution to eliminate SQL injection and command injection risks.
  • Web Security Hardening: Apply XSS/CSRF protection, secure session configuration, and context-aware output encoding for Perl web frameworks including CGI, Mojolicious, Dancer2, and Catalyst.
  • Security Tooling Integration: Configure perlcritic security policies to automatically flag vulnerable code patterns during development and CI pipelines. Use case: A developer building a Perl-based user authentication system can use this skill to validate login input, prevent SQL injection in database queries, and sanitize output to block XSS attacks.

Quick Start

Use the perl-security skill to audit your existing Perl web application code for injection vulnerabilities and implement taint mode and input validation safeguards.

Frequently Asked Questions about perl-security

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

FAQPage Schema
How do I prevent SQL injection in Perl DBI database operations?▼

Prevent SQL injection in Perl DBI database operations by implementing parameterized queries with placeholders, ensuring user input is strictly separated from SQL execution logic.

How does taint mode enforce input validation in Perl web applications?▼

Taint mode enforces input validation in Perl web applications by marking all external input as tainted and requiring explicit sanitization through allowlist-based validation before the data can be used in dangerous operations.

How do I sanitize user input to prevent XSS in Mojolicious and Dancer2?▼

To prevent XSS in Mojolicious and Dancer2, apply context-aware output encoding to sanitize user input, ensuring malicious scripts are rendered as plain text rather than executed by the browser.

What is the best way to configure perlcritic security policies to flag vulnerable Perl code?▼

The best way to configure perlcritic security policies is to integrate them into your development workflow and CI pipelines to automatically flag vulnerable Perl code patterns during code reviews.

Does this approach work for preventing command injection during Perl system command execution?▼

Yes, preventing command injection during Perl system command execution requires using safe list-form process execution, which avoids shell interpretation and securely passes arguments as separate list elements.

Can I apply these secure coding practices to legacy CGI scripts?▼

Yes, you can apply these secure coding practices to legacy CGI scripts by auditing existing code for injection vulnerabilities and implementing taint mode, input validation, and output encoding safeguards.
