Security Audit Report

Last Audited: 2026-01-04 Audited By: Claude (Opus 4.5) + Human Review Status: Passed - No security issues found

Overview

This document provides a security audit of all scripts in this repository. All scripts have been reviewed for:

• Command injection vulnerabilities
• Dangerous shell commands (rm -rf, sudo, etc.)
• Unauthorized network calls / data exfiltration
• eval() / exec() misuse
• Credential harvesting

Result: All scripts are safe for use.

Subprocess Calls Analysis

All subprocess calls use array-based commands (not shell=True), preventing command injection:

# Safe pattern used throughout (no shell injection possible)
subprocess.run(['soffice', '--headless', '--convert-to', 'pdf', filename])

# NOT used (would be vulnerable)
subprocess.run(f'soffice --headless {filename}', shell=True)  # NEVER USED

What We Verified Does NOT Exist

• No eval() or exec() with user input
• No rm -rf or destructive file operations
• No curl | bash or remote code execution
• No hardcoded credentials or API keys
• No network calls that exfiltrate data
• No obfuscated or encrypted code

External Dependencies

All scripts use well-known, trusted libraries:

How to Verify

You can verify this audit yourself:

# Search for potentially dangerous patterns
grep -r "eval\|exec\|subprocess.*shell=True\|rm -rf\|curl.*\|" --include="*.py" .

# Check all subprocess calls
grep -r "subprocess" --include="*.py" -A 3 .

# Verify no network calls in Python scripts
grep -r "requests\|urllib\|http.client" --include="*.py" .

Disclaimer

This audit covers the scripts as of the audit date. Always review code before running it in sensitive environments. If you find any security issues, please report them via GitHub Issues.
