This vulnerability in Google Chrome's Media component on Windows allows a remote attacker with control over the renderer process to bypass the same origin policy by using a specially crafted HTML page. The flaw is classified under CWE-346 (Origin Validation Error). The issue affects Chrome versions prior to 151.0.7922.72. The CVSS 3.1 base score is 6.5 (medium severity), reflecting network attack vector, low attack complexity, no privileges required, user interaction required, unchanged scope, no confidentiality impact, high integrity impact, and no availability impact. There is no explicit remediation level stated, but the affected versions indicate that version 151.0.7922.72 addresses the issue.
