CVE-2022-3444Network attack vector

File restriction bypass via insufficient input validation

Published Nov 1, 2022 · Updated Aug 3, 2024

Insufficient input validation in Google Chrome's File System API before 106.0.5249.62 allows remote attackers to bypass file restrictions. The public advisory does not identify the validation locus or explain how the crafted HTML page and malicious file evade the API's file-system boundary checks. Exploitation requires user interaction with attacker-controlled web content and a malicious file and permits operations outside intended file restrictions, not code execution or service interruption.
