Caution
Description: Potential hardcoded credential detected. This code may contain sensitive data such as passwords or API keys embedded directly in the source. Hardcoded credentials can be extracted and misused, leading to unauthorized access to systems or data breaches. To remediate this, store secrets in environment variables or use a secrets management tool like AWS Secrets Manager, Azure Key Vault, or HashiCorp Vault. Avoid committing credentials to version control. For best practices, refer to - https://owasp.org/www-community/vulnerabilities/Use_of_hard-coded_password
Severity: Critical

The fix replaces hardcoded credentials with environment variables, which are retrieved using os.environ.get(). This approach securely stores sensitive information outside the codebase and allows for easier management of credentials across different environments.

Caution
Description: This code is vulnerable to code injection because it executes user-controlled input without proper validation or sanitization. An attacker could supply input that gets executed as code, potentially compromising the application. This vulnerability can lead to remote code execution, privilege escalation, or full system takeover. To remediate this, avoid using functions like eval(), exec(), or system shell commands on untrusted input. In Python, prefer ast.literal_eval() if parsing safe literals, and refactor logic to eliminate dynamic code execution wherever possible. Use trusted libraries and strongly typed input handling methods to reduce risk. More information - https://owasp.org/www-community/attacks/Code_Injection

The fix replaces the unsafe pickle.loads() with json.loads(), which is a safer method for deserializing data. The received bytes are first decoded to UTF-8 before parsing as JSON, ensuring secure handling of untrusted input.
| pickle.loads(data) | |
| def negative_loads_request(): | |
| data = bytes(requests.get("https://data.bytes")) | |
| # Use json.loads() instead of pickle.loads() for safe deserialization | |
| # import json | |
| parsed_data = json.loads(data.decode('utf-8')) | |
| return parsed_data |

The remediation involves replacing hardcoded credentials with calls to os.getenv() to retrieve the values from environment variables. This approach enhances security by keeping sensitive information out of the source code.
| aws_access_key_id = "BjWnyxxxxx45xxxxZxxxX7ZQxxxxYxxx1xYxxxxx" | |
| import os # Import os module to access environment variables | |
| def create_session_noncompliant(): | |
| # Compliant: Retrieves credentials from environment variables | |
| aws_access_key_id = os.getenv("AWS_ACCESS_KEY_ID") | |
| aws_secret_access_key = os.getenv("AWS_SECRET_ACCESS_KEY") | |
| aws_session_token = os.getenv("AWS_SESSION_TOKEN") | |
| session = boto3.session.Session( | |
| aws_access_key_id=aws_access_key_id, |

The fix replaces the use of pickle.loads() with json.dumps() and json.loads(), which are safer alternatives for serialization and deserialization. This eliminates the risk of arbitrary code execution associated with pickle.loads().
| pickle.loads(tmp) | |
| def positive_dumps_loads(): | |
| data = bytes(requests.get("https://data.bytes")) | |
| tmp = pickle.dumps(data) | |
| # Use json for safe serialization and deserialization | |
| # import json | |
| json_data = json.dumps(data.decode()) | |
| json.loads(json_data) |

The fix replaces the hardcoded password with a call to os.getenv() to retrieve the password from an environment variable. This approach improves security by keeping sensitive information out of the source code.
| password = "password" | |
| import os # Import os module to access environment variables | |
| def non_compliant(): | |
| # Noncompliant: Hardcoded secrets might allow unauthorized users to access your account. | |
| password = os.getenv("PASSWORD_ENV_VAR") # Retrieve password from environment variable |

✅ I finished the code review, and left comments with the issues I found. I will now generate code fix suggestions. |
