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.runwithshell=Trueand 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=Trueinsubprocess.runwhenever possible, especially when dealing with user input. - Always sanitize and validate user input before using it in system commands or queries.

Critical The generate_report function is vulnerable to command injection.

🔴 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.
| command = f"pandoc {content_file} -o report.pdf --metadata title='{report_title}'" | |
| result = subprocess.run(command, shell=True, capture_output=True, text=True) | |

| content_file, | |
| "-o", | |
| "report.pdf", | |
| "--metadata", | |
| f"title={report_title}", | |
| ] | |
| result = subprocess.run(command, capture_output=True, text=True, check=True) |

📋 Security Summary
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.
🔍 General Feedback
- The script is simple and easy to understand.
- The use of
subprocess.runwithshell=Trueis dangerous and should be avoided. - It is recommended to always sanitize user input before using it in shell commands.
📋 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.

| result = subprocess.run(command, capture_output=True, text=True) |
