CVE-2024-23280Network attack vector

User fingerprinting via insufficient WebKit injection validation

Published Mar 8, 2024 · Updated Apr 2, 2026

WebKit injection in Safari before 17.4 and affected Apple platforms allows remote attackers to fingerprint users via crafted webpages. Apple identifies WebKit Bugzilla issue 266703 and inadequate injection validation but has not disclosed the input field or downstream operation. Exploitation requires processing attacker-controlled web content; the reported consequence is browser fingerprinting, not code execution or data modification.
