What is CVE-2019-8827?

The vulnerability involves an improper handling of the HTTP referrer header that may expose users' browsing history to malicious sites. When a user visits a crafted website, sensitive information about previously visited sites can potentially be leaked, which raises significant privacy concerns. Apple addressed the issue by implementing measures to ensure that all third-party referrers are downgraded to their origin, effectively mitigating the risk in various products including Safari and iTunes.
