Address bar spoofing via interrupted cross-origin navigation
Published Feb 27, 2020 · Updated Aug 4, 2024
Address bar spoofing in Apple Safari before 13.0.5 allows remote attackers to display malicious content under a trusted URL. A crafted page opens a window, starts navigation to a trusted origin on an invalid port, and immediately writes attacker-controlled markup while Safari retains the target URL. Exploitation requires user interaction with the malicious page; the resulting mismatch can make attacker-controlled content appear attributable to a trusted site.
