python_sdk

The SDK itself does not contain obvious direct code execution vulnerabilities (e.g., 'eval'). However, it relies heavily on external HTTP services (PayLink MCP server, wallet.paylinkai.app, evaluator.paylinkai.app). The security of the overall system depends critically on the trustworthiness and security of these external services, as well as the secure handling and transmission of sensitive credentials like 'WALLET_CONNECTION_STRING' (e.g., via HTTPS). If the 'PAYMENT_PROVIDER_HEADER' environment variable is maliciously crafted with invalid JSON, it could cause runtime errors, though it's not likely to lead to arbitrary code execution as the parsed data is used for string comparisons. Default external service URLs are hardcoded but can be overridden.
