CVE-2020-6502Network attack vector

Security UI spoofing via crafted HTML page

Published Jun 3, 2020 · Updated Aug 4, 2024

Incorrect security UI in Google Chrome before 80.0.3987.87 allows remote attackers to spoof permission indicators via a crafted HTML page. Google identifies the affected locus only as permissions and has not published the incorrect permission-handling operation. A user must open the crafted page; the resulting deception alters security-relevant UI without reported data disclosure or service interruption.
