SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Perl applications often suffer from critical security vulnerabilities such as SQL injection, cross-site scripting (XSS), command injection, and path traversal when developers lack standardized, enforceable secure coding practices, particularly when handling untrusted user input, executing system commands, or querying databases.

Core Features & Use Cases

  • Taint mode enforcement: Provides clear, actionable patterns for enabling and leveraging Perl's built-in taint mode to track external input and block unsafe operations until data is explicitly validated.
  • Injection prevention: Includes allowlist-based input validation rules, safe DBI parameterized query templates, and list-form process execution guidelines to eliminate SQLi, command injection, and regular expression denial of service (ReDoS) risks.
  • Web security guardrails: Covers XSS output encoding, CSRF token generation, secure session configuration, and security header implementation for popular Perl web frameworks including Mojolicious, Dancer2, and Catalyst.
  • Use case: A solo developer building a Perl-based customer self-service portal can use this skill to implement secure user authentication, safe file upload handling, and protected database queries without introducing common security flaws.

Quick Start

Use the perl-security skill to audit your existing Perl web script for taint mode compliance, input validation gaps, and SQL injection risks before you deploy it to production.

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 scripts?▼

To prevent SQL injection in Perl DBI scripts, use parameterized query templates with placeholders instead of string interpolation. This Skill provides safe DBI execution patterns that separate user input from SQL command logic.

How does Perl taint mode work for securing external input?▼

Perl taint mode tracks external input and blocks unsafe operations like file writes or system calls until the data is explicitly validated. This skill provides actionable patterns for enabling taint mode and enforcing allowlist-based input validation.

Can I use this to add XSS protection headers and CSRF tokens in Mojolicious?▼

Yes, this covers web security guardrails for Mojolicious, Dancer2, and Catalyst. It implements XSS output encoding, secure session configuration, CSRF token generation, and security headers for Perl web frameworks.

What is the best way to audit existing Perl code for command injection risks?▼

The best way to audit Perl code for command injection is to review process execution calls and enforce list-form execution guidelines. This Skill checks for unsafe system command execution and applies security-focused perlcritic policies.

Do I need perlcritic to enforce secure coding standards in Perl?▼

You need perlcritic to enforce secure coding standards by detecting insecure patterns automatically. This Skill satisfies requirements for compliance with security-focused perlcritic policies for production-grade Perl code.
