I think this fies/workaround the issue:
https://cgit.freebsd.org/ports/commit/?id=f3e4dbcb5ff2fe2a018f78f396a4247f1dd32cc9

I changed the affected version from < 3.7.4 to <= 3.7.3. Now both
3.7.4 and 3.7.4.p0 (3.7.4.post0) are not affected.

Although in ports' version 3.7.4 is newer than 3.7.4.p0, we don't have
3.7.4 in the history of www/py-aiohttp so no PORTEPOCH is needed.

Best,
