CVE-2026-64730 is a WebKit user-interface spoofing vulnerability. A website that frames attacker-controlled malicious content can cause misleading or spoofed UI to be displayed, potentially making untrusted content appear to originate from a trusted browser or application context. The issue was corrected through improved UI handling and protections. It affects WebKitGTK and WPE WebKit releases before 2.52.6 and was also fixed in Safari 26.6 and Apple operating-system releases incorporating the corresponding WebKit fix.
