CVE-2019-8649

26
FAUCET Score

CVE-2019-8649 describes a universal cross-site scripting (UXSS) vulnerability stemming from a logic issue in how synchronous page loads were handled in WebKit. This flaw affected multiple Apple products, including iOS, macOS, tvOS, Safari, iTunes for Windows, and iCloud for Windows. With a CVSS score of 6.1 (Medium), exploitation requires user interaction (UI:R) and could lead to information disclosure and data manipulation (C:L, I:L) if a user processes maliciously crafted web content. While not listed on the KEV catalog or Hot List, public exploit code (EDB-47162) exists, though there is no evidence of widespread active exploitation or significant community discussion.
