CVE-2023-1823Network attack vector

Navigation restriction bypass via crafted HTML

Published Apr 4, 2023 · Updated Feb 13, 2025

Navigation restriction bypass in Google Chrome before 112.0.5615.49 allows remote attackers to evade FedCM controls via crafted HTML. The restricted Chromium issue does not disclose which FedCM code path incorrectly permits the navigation, so the underlying validation or policy-enforcement error is not public. Exploitation requires user interaction with an attacker-controlled page and alters navigation behavior without reported data disclosure or service interruption.
