Overview

Quart is an A Python ASGI web microframework with the same API as Flask

Affected versions of this package are vulnerable to Insertion of Sensitive Information into Log File in the __await__ method of src/quart/wrappers/request.py, where a debug print(data) statement causes the raw bytes of every incoming request body to be written to standard output. An unauthenticated remote attacker can exfiltrate sensitive request body content - including credentials, tokens, or personal data - by sending any HTTP request whose body is processed by the server, provided the application's standard output is observable (e.g. via logs, a terminal, or a process supervisor).
