Technical details

A cross-origin data leak vulnerability exists in Google Chrome for iOS prior to version 151.0.7922.72. The flaw stems from an inappropriate implementation in the browser's UI handling, which fails to strictly enforce origin boundaries during certain user interactions. A remote attacker can exploit this by convincing a user to engage in specific UI gestures on a malicious HTML page, potentially allowing the attacker to bypass Same-Origin Policy (SOP) protections and read data from other origins. This issue is addressed in the stable channel update 151.0.7922.72.
