## 📋 Security Summary

This pull request introduces a new Python script for generating PDF reports. The script contains a critical command injection vulnerability due to improper handling of user input when constructing a shell command.

🔍 General Feedback

The script's functionality is straightforward, but the use of subprocess.run with shell=True and un-sanitized user input poses a significant security risk. It is crucial to address this vulnerability before merging.

This pull request introduces a new Python script for generating PDF reports. The script contains a critical command injection vulnerability that allows remote code execution.

🔍 General Feedback

It is highly recommended to avoid using shell=True in subprocess.run whenever possible, especially when dealing with user input.
Always sanitize and validate user input before using it in system commands or queries.

This pull request introduces a new Python script for generating PDF reports. The script is vulnerable to command injection, which allows an attacker to execute arbitrary commands on the system.

🔍 General Feedback

The script uses user input directly in a shell command, which is a critical security risk.

The script should be updated to use shell=False and pass the command and its arguments as a list to subprocess.run.

🔴 The use of shell=True with user-provided input in the subprocess.run function creates a command injection vulnerability. A malicious user could provide a crafted report title to execute arbitrary commands on the system.

To fix this, you should pass the command as a list of arguments to subprocess.run and avoid using shell=True. This ensures that user input is treated as a single argument and not interpreted by the shell.

This pull request introduces a new Python script for generating PDF reports. The script is vulnerable to command injection, which is a critical security issue. The vulnerability allows an attacker to execute arbitrary commands on the system where the script is run.

📋 Review Summary\n\nThis pull request introduces a Python script for generating PDF reports. The initial review has identified a critical security vulnerability that must be addressed before merging.\n\n## 🔍 General Feedback\n\n- Critical Security Vulnerability: The script is vulnerable to command injection because it uses untrusted user input to construct a shell command. This has been flagged in the inline comments with a detailed explanation and a suggested fix.\n- Dependencies: The script assumes `pandoc` is installed and available in the systems PATH. It would be beneficial to add a `README.md` or comments mentioning this dependency.

An attacker can inject arbitrary commands by crafting a malicious report title. You should use shlex.quote() to sanitize the user-supplied input.

🔴 Critical: This line constructs a shell command using raw user input, which creates a severe command injection vulnerability. A malicious title like '; rm -rf / could execute arbitrary commands. The command should be constructed as a list of arguments to be passed to subprocess.run safely.

🔴 Critical: Executing a command with shell=True using unvalidated user input is extremely dangerous and leads to command injection. After modifying the command to be a list of arguments, you must remove shell=True to execute the command safely. Using check=True is also recommended to automatically raise an exception if the command fails.
