CVE-2022-32868Network attack vector

User tracking via unmasked extension URLs

Published Sep 20, 2022 · Updated Aug 3, 2024

Information disclosure in Apple Safari before 16 and affected iOS or iPadOS releases allows remote attackers to track users. JavaScriptCore exposed masked extension source URLs in Error.stack because StackFrame string conversion returned the original URL instead of consulting WebCore's URL-masking logic. A user must visit attacker-controlled web content while a Safari web extension is enabled; the disclosed extension URL enables cross-site tracking, not content modification or service interruption.
