• nhonga_api/client.py: Applied 3 critical security and correctness fixes: (1) Added hmac import for secure comparison, (2) Corrected base URL from vendorapay.com to nhonga.net to fix broken API integration, (3) Replaced vulnerable string comparison with hmac.compare_digest() to prevent timing attacks on webhook validation
• nhonga_api/examples.py: Accepted only security warning patches. Typo fixes ('enviroment' -> 'environment') deferred until types.py is updated to maintain consistency - types.py still defines 'enviroment' in CreatePaymentRequest.
• nhonga_api/types.py: Corrected a critical typo in the CreatePaymentRequest TypedDict that would cause the environment field to be mismatched with the actual API expectations, potentially leading to unintended behavior like defaulting to production.

Summary

README.md:

• ⚠️ Insecure API credential handling in examples (credentials shown as plaintext)
• ⚠️ Typo 'enviroment' instead of 'environment' in multiple code examples (lines 37, 199, 230) - will cause runtime errors if copied
• ⚠️ Missing TLS validation mention in security considerations

nhonga_api/init.py:

• ⚠️ Insecure API credential handling (potential issue in client.py)
• ⚠️ Missing TLS validation (potential issue in client.py)

nhonga_api/client.py:

• ⚠️ Vulnerabilidade de timing attack na validação de webhook (linha 152) - comparação simples de strings pode permitir inferência da chave secreta
• ⚠️ URL base hardcoded aponta para vendorapay.com em vez de nhonga.net (linha 32) - possível erro de configuração ou endpoint incorreto
• ⚠️ Mensagens de erro podem expor informações sensíveis do servidor (linha 63)
• ⚠️ Sem retry logic para requisições HTTP falhas

nhonga_api/examples.py:

• ⚠️ Insecure API credential handling: Hardcoded placeholder credentials ('SUA_CHAVE_API', 'SUA_CHAVE_SECRETA') may encourage unsafe practices in production if not replaced properly.
• ⚠️ Typo in key name 'enviroment' (missing 'n') in payment request dictionaries could cause runtime errors or unexpected behavior if the API expects 'environment'.

nhonga_api/types.py:

• ⚠️ Typo in field name 'enviroment' (line 48) may cause runtime mismatches or ignored configuration
• ⚠️ Insecure credential handling if NhongaConfig is logged or exposed (api_key/secret_key)
• ⚠️ Lack of validation on enum values when deserializing API responses could lead to unexpected behavior

requirements.txt:

• ⚠️ Dependency supply chain risks
• ⚠️ Potential version incompatibilities if upper bounds are not specified

setup.py:

• ⚠️ Dependency version constraints may be too permissive (>=2.25.0) allowing potentially vulnerable versions
• ⚠️ No explicit license file reference in setup.py
• ⚠️ Development dependencies could introduce supply chain risks if not properly vetted
