CVE-2026-64753Network attack vector

Sensitive information disclosure via WebKit permissions flaw

Published Sep 14, 2026 · Updated Sep 14, 2026

Information disclosure in Apple Safari and operating systems before 27 allows remote attackers to read sensitive user information via web content. WebKit applies incorrect permissions while processing attacker-controlled content; Apple identifies Bugzilla 315121 but does not disclose the removed code or failed check. Viewing attacker-controlled web content is required, and the reported consequence is disclosure without reported data modification or service interruption.
