While I agree, it makes connecting to localhost as easy as
http://0:8080/(for port 8080, but omit for port 80).I worry that changing this will cause more CVEs like the octal IP addresses incident.
Edit: looks like it's only being blocked for outgoing requests from websites, which seems like it'll have a much more reasonable impact.
Edit 2: skimming through these PRs, at least for WebKit, I don't see tests for shorthand IPs like
0(and no Apple device to test with). What are the chances they missed those..?The thing is that it's not supposed to work, so it's essentially relying on undefined behaviour. Typing
[::1]:8080is nearly as easy.I haven't seen the PRs, but IP comparison should really be using the binary form of the IPv4 address (a 32-bit number), not the human-friendly form.
