SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Perl applications are frequently targeted for injection attacks, taint mode misuses, and unsafe file or process operations that lead to data breaches, unauthorized code execution, and system compromise. This Skill provides actionable, production-ready security guidelines to eliminate these common vulnerabilities in Perl codebases.

Core Features & Use Cases

  • Taint Mode & Input Validation: Enforce allowlist-based input validation and proper untainting to block malicious user-supplied data from being used in unsafe operations.
  • Injection Prevention: Provide safe, vetted patterns for DBI parameterized queries, list-form process execution, and ReDoS-resistant regular expressions to stop SQL injection, command injection, and regex denial-of-service attacks.
  • Web Security Hardening: Cover XSS output encoding, CSRF protection, secure session configuration, and security header implementation for Perl web frameworks including CGI, Mojolicious, Dancer2, and Catalyst.
  • Use Case: A developer building a Perl-based user registration form can use this Skill to implement taint mode, validate and untaint user input, safely store user data in a database with parameterized queries, and encode output to prevent XSS attacks.

Quick Start

Use the perl-security skill to audit your existing Perl web application code for taint mode compliance, unvalidated user input, and unsafe database query patterns.

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 queries?▼

Preventing SQL injection in Perl DBI database queries requires using parameterized queries with placeholders instead of string interpolation. This Skill provides vetted patterns to ensure user-supplied input is safely bound to database operations, blocking malicious execution.

What is Perl taint mode and how do I untaint user input correctly?▼

Perl taint mode marks user-supplied data as unsafe to block dangerous operations. You untaint input correctly by enforcing allowlist-based validation and extracting known-safe patterns, which this Skill provides as actionable compliance guidelines for secure coding.

How do I prevent XSS in Mojolicious, Dancer2, and Catalyst web frameworks?▼

Preventing XSS in Mojolicious, Dancer2, and Catalyst requires proper output encoding and security header implementation. This Skill covers web security hardening, including XSS output encoding and CSRF protection tailored for Perl web development frameworks.

What is the best way to prevent command injection during Perl process execution?▼

The best way to prevent command injection during Perl process execution is using list-form process execution instead of shell interpolation. This Skill provides safe patterns for process execution to stop unauthorized code execution and system compromise.

Does this cover security policy configuration for Perl::Critic?▼

Yes, it covers security policy configuration for Perl::Critic. This Skill helps configure Perl::Critic security policies to audit existing codebases, enforcing secure coding practices for input handling, filesystem operations, and database interactions.

How do I secure filesystem operations with user-supplied input in Perl?▼

Securing filesystem operations with user-supplied input in Perl requires strict taint mode compliance and allowlist validation before file access. This Skill enforces secure coding practices to eliminate unsafe file operations that lead to data breaches.
