Summary
The Keychain implementation in Apple Mac OS X 10.6.8 and earlier does not properly handle an untrusted attribute of a Certification Authority certificate, which makes it easier for man-in-the-middle attackers to spoof arbitrary SSL servers via an Extended Validation certificate, as demonstrated by https access with Safari.
Exploit prediction
0.86% chance of exploitation in the next 30 days, higher than 58% of all scored CVEs (FIRST EPSS, 2026-11-09).
