CVE-2023-29334Network attack vector

Security UI spoofing via crafted HTML

Published Apr 28, 2023 · Updated Feb 28, 2025

Spoofing in Microsoft Edge (Chromium-based) before 112.0.1722.48 allows remote attackers to falsify security UI after user interaction. Crafted HTML content causes the browser to display attacker-controlled content within its security warning interface, allowing the warning to be bypassed. The user must visit the crafted page; the consequence is limited to misrepresentation of browser security information.
