CVE-2020-6472Network attack vector

Sensitive memory and disk information disclosure

Published May 21, 2020 · Updated Aug 4, 2024

Information disclosure in Google Chrome before 83.0.4103.61 allows remote attackers to read sensitive process memory or disk data. Google describes insufficient policy enforcement in developer tools but has not disclosed the affected policy check or the operation that exposes the data. Exploitation requires convincing a user to install a crafted malicious extension, and the documented consequence is limited to confidentiality loss.
