BaseRequest.url passes the host and port to URL.build when the port is included in the host header (non-default port) -- fixed in 3.10.7 #9307
Description
request.host can be 127.0.0.1:8123
aiohttp/aiohttp/web_request.py
Line 447 in 0b8be7f
yarl 1.13.0+ caught this because host is now validated via aio-libs/yarl#954
Pinning yarl to < 1.13.0 will also prevent the issue since the validation doesn't happen until that version.
