CVE-2023-0140Network attack vector

File system restriction bypass

Published Jan 10, 2023 · Updated Aug 2, 2024

An implementation flaw in Google Chrome on Windows before 109.0.5414.74 allows remote attackers to bypass file system restrictions. Google identifies the affected locus as the File System API, but the restricted issue record leaves the incorrect operation on untrusted input undisclosed. Exploitation requires a user to load a crafted HTML page; the documented consequence is unauthorized file-system access rather than disclosure or service interruption.
