Description When using the `NoPrivateNetworkHttpClient`, some internal information is still leaking during host resolution, which leads to possible IP/port enumeration. Resolution The `NoPrivateNetworkHttpClient` now filters blocked IPs earlier to prevent such leaks. The fisrt patch for this issue is available here for branch 5.4. The second one is available here for branch 5.4 also. Credits We would like to thank Linus Karlsson and Chris Smith for reporting the issue and Nicolas Grekas for providing the fix.
