Can it help me fix vulnerabilities in legacy Perl scripts?

Yes, it provides specific patterns for enabling taint mode (-T) and refactoring dangerous two-argument open calls into secure three-argument versions.

How does it handle execution of external system commands?

It promotes using the list-form of system() and exec(), which bypasses the shell and prevents shell metacharacter injection attacks.

How does this skill help prevent SQL injection in Perl?

The skill enforces the use of DBI placeholders and parameterized queries, ensuring that user input is never directly interpolated into SQL strings.

Does this skill cover web-specific security like XSS and CSRF?

Absolutely. It includes best practices for HTML entity encoding, CSRF token generation, and secure session management for popular frameworks like Mojolicious.

Security & Testing

Implements comprehensive security patterns for Perl applications, including taint mode, SQL injection prevention, and secure process execution.

The perl-security skill equips Claude with the domain-specific knowledge required to harden Perl applications against common vulnerabilities. It provides actionable patterns for taint-aware input handling, three-argument file operations, parameterized DBI queries, and cross-site scripting (XSS) prevention. This skill is essential for developers maintaining legacy CGI scripts or building modern web applications with frameworks like Mojolicious and Catalyst, ensuring that code follows the highest security standards and passes rigorous perlcritic security audits.

Key Features

01Safe file operations using three-argument open and path traversal protection
