SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Perl applications are highly vulnerable to critical security flaws including injection attacks, cross-site scripting, and unsafe system interactions when secure coding practices are not enforced, leading to data breaches, unauthorized access, and system compromise.

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 list-form process execution to eliminate SQL injection and command injection risks.
  • Web Security Hardening: Add XSS protection, CSRF tokens, and secure HTTP headers for Perl web frameworks including CGI, Mojolicious, Dancer2, and Catalyst.
  • Use Case: A Perl developer building a user authentication system can use this skill to validate login input, prevent SQL injection in user lookup queries, and escape output to block XSS attacks in error messages.

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 queries?▼

To prevent SQL injection in Perl DBI, use parameterized queries with placeholders instead of string interpolation. This ensures user input is treated strictly as data rather than executable SQL code, eliminating database query manipulation risks.

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

Taint mode in Perl marks all external input as unsafe until explicitly validated. By enforcing allowlist-based input validation, it blocks malicious payloads from reaching sensitive operations like file access or system command execution.

Does this approach support securing Mojolicious, Dancer2, and Catalyst frameworks?▼

Yes, this approach secures Mojolicious, Dancer2, Catalyst, and CGI frameworks. It applies context-appropriate output encoding, CSRF tokens, and secure HTTP headers to prevent cross-site scripting and web vulnerabilities across Perl web platforms.

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

The best way to prevent command injection during Perl system execution is using list-form process execution. Passing arguments as a list rather than a single string avoids shell interpolation, safely isolating parameters from executable command logic.

How do I sanitize external input and prevent XSS in Perl CGI scripts?▼

To prevent XSS in Perl CGI scripts, implement strict input sanitization alongside context-appropriate output encoding. Validating external input against allowlists and escaping output data blocks malicious scripts from executing in user browsers.
