File access bypass via insufficient input validation
Published May 2, 2023 · Updated Feb 13, 2025
Insufficient input validation in Google Chrome before 113.0.5672.63 allows attackers to bypass file access checks through crafted HTML. Google identifies the Extensions component but has not published the validation path or the specific file-access decision that accepts the page input. Exploitation requires a user to install a malicious extension and then process crafted HTML, exposing files beyond the extension’s intended access.
