Summary
The CFNetwork HTTPProtocol component in Apple iOS before 9 and OS X before 10.11 does not properly recognize the HSTS preload list during a Safari private-browsing session, which makes it easier for remote attackers to obtain sensitive information by sniffing the network.
Exploit prediction
1.45% chance of exploitation in the next 30 days, higher than 73% of all scored CVEs (FIRST EPSS, 2026-11-09).
