The code exposes hardcoded AWS credentials in environment variables. An attacker can use these credentials to gain unauthorized access to AWS services, potentially leading to data leakage or complete system compromise.
Impact:
An attacker with the hardcoded credentials could perform any action on the affected AWS account, including reading and writing data, accessing other accounts, and more.
Mitigation:
Use a secure method for managing secrets such as AWS Secrets Manager, environment variables securely encrypted at rest using tools like HashiCorp Vault or AWS KMS, and avoid hardcoding credentials in source code. For example, use os.getenv('S3_ACCESS_KEY', 'default_access_key') to provide a default value.

Impact:
An attacker could exploit this vulnerability to execute arbitrary code on the server, leading to a complete compromise of the system. The severity is high because deserialization flaws often allow attackers to bypass access controls and achieve remote code execution.
