Published: 02 January 2023
Summary
CVE-2022-0337 is a medium-severity Exposure of Resource to Wrong Sphere (CWE-668) vulnerability in Google Chrome. Its CVSS base score is 6.5 (Medium).
Operationally, ranked in the top 6.1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
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.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Controls whether organization resources are exposed to external system spheres by permitting or prohibiting their use.
The control ensures information is not released into a security sphere where the recipient lacks matching access authorizations.
The control ensures information resources are not exposed to the incorrect (public) sphere through review and authorization.
Protects against data mining that would expose resources to unauthorized spheres by enforcing detection and controls.
Restricts information flows to ensure resources are not exposed to incorrect or unauthorized spheres.
Controlling internal connections prevents exposure of resources to unintended internal spheres.
Knowing exact processing and storage locations helps avoid exposure of resources to incorrect spheres.
The control prevents exposure of the media resource to the wrong security sphere.
