Deeper analysis

CVE-2022-0337 is an inappropriate implementation flaw in the File System API of Google Chrome on Windows, affecting versions prior to 97.0.4692.71. The issue is tracked under CWE-668 and carries a CVSS 3.1 score of 6.5, reflecting network attack vectors with low complexity that can result in high confidentiality impact.

A remote attacker can exploit the vulnerability by serving a crafted HTML page to a victim, enabling unauthorized access to potentially sensitive information stored via the File System API without requiring user privileges beyond normal browser interaction.

Chrome stable channel updates released in January 2022 address the flaw by updating the affected File System API implementation; users are advised to upgrade to version 97.0.4692.71 or later to eliminate exposure.

The associated EPSS score rose from a low baseline to a peak of 0.3070 on 2025-12-11 before receding to the current value of 0.1173, indicating a period of increased exploitation interest after disclosure.
