Navigation restriction bypass via crafted domain name

Published Feb 11, 2020 · Updated Aug 4, 2024

Navigation restriction bypass in Google Chrome before 80.0.3987.87 allows remote attackers to evade restrictions via a crafted domain name. The Omnibox mishandles the crafted domain name in a user-entered URI, but Google has not disclosed the responsible function or validation error. Exploitation requires convincing a user to enter the URI and is bounded to navigation-policy bypass; no code execution or data access is reported.
