CVE-2015-3754: Apple Safari

Medium severity, CVSS 4.3. EPSS: 1.9% chance of exploitation in the next 30 days.

The private-browsing implementation in WebKit in Apple Safari before 6.2.8, 7.x before 7.1.8, and 8.x before 8.0.8 does not prevent caching of HTTP authentication credentials, which makes it easier for remote attackers to track users via a crafted web site.

Affected products

• Apple Safari: from 6.0, before 6.2.8 (fixed in 6.2.8); from 7.0, before 7.1.8 (fixed in 7.1.8); from 8.0, before 8.0.8 (fixed in 8.0.8)
