AIOHTTP: Absolute-form request targets can spoof Request.scheme
### Summary An attacker sending an absolute-form request can spoof the scheme used. ### Impact If user code depends on the `Request.scheme` attribute for anything security related, an attacker may be able to circumvent this logic, tricking the application into thinking a connection is encrypted when it is not, or vice versa. ### Workaround A WAF rule to reject absolute-form requests (legitimate requests should only use this form for proxies).
