Doc Text:
A flaw was found in chromium-browser. A coding error within the file picker component allows a remote attacker to trigger a cross-origin data leak by manipulating user interface gestures through a specially crafted HTML page. This manipulation allows the attacker to access data from other origins. The vulnerability requires user interaction to trigger the data leak. Consequently, an attacker can expose sensitive information.
