There was at least one other Private Relay issue that doesn’t seem to have received much public attention.

I found and reported an IP leak to Apple in December 2025. The issue was caused by an EDNS Client Subnet (ECS) configuration problem in Akamai’s infrastructure, which could result in the client’s real IP being forwarded when it shouldn’t have been.

Apple confirmed the fix at the end of March 2026, and then I unexpectedly received a $5,000 Security Bounty in July.
